Data loggers are electronic instruments that records data over time, either through integrated software and features or through other instruments or sensors. Data loggers are often constructed from durable materials are expected to be able to withstand being exposed to certain conditions such as outdoor weather conditions, being submerged in water or extreme heat.
Conductivity data loggers are designed specifically to track and record the electrical conductivity within a medium. Often, these loggers would have other functions such as measuring temperature or salinity depending on the medium being studied.
Depth loggers are specifically designed to record water level. Specific models are available for fresh and salt water, but many models of depth loggers can be used in both areas without problems. As with most data loggers, depth loggers can also record other functions related to their intended environment. For instance, most depth logger model can also record temperature and pressure, two significant measures for bodies of water.
Dissolved Oxygen loggers are data loggers that measure and records the oxygen concentration in liquids, especially in bodies of water. Dissolved oxygen concentration as an important parameter that helps assess the viability of the liquid in supporting organic life. Bodies of liquid that have low dissolved oxygen measures cannot support life, while high measures of dissolved oxygen ensures that organic life will thrive and propagate. Dissolved Oxygen loggers are mainly used for environment studies and in the fishing industry, especially with fresh water fishes since this type is more sensitive to changes in dissolved oxygen compared to salt-water fishes.
Event loggers are specialized data loggers that only record certain data that fall within a set parameter and also records moments where change occurred within the measured environment. Event loggers are designed to record these events with a time stamp (time and date when the event occurred). And keep a tally on how many of these events took place within a given time period.
Possible applications of event loggers are in monitoring water and gas flows, energy consumption, mechanical equipment operation and monitoring electrical activity and electronic pulses.
Gas loggers make periodic measurement and recording of the concentration of different gases in the atmosphere. This type of data loggers are used in monitoring ventilation in different work spaces and in the home. A lack of proper air ventilation can result into the accumulation of hazardous gases such as Carbon dioxide that can various health problems, making it important to have gas loggers to ensure that these gases remain within safe levels.
Most gas loggers are specifically designed to detect and monitor specific gases, while others can detect more than one type of gas. Gas loggers that can monitor multiple gases are generally designed for a specific application in mind. For instance, there are gas loggers that can monitor both carbon dioxide and nitrogen levels since these are the two primary hazardous gases that can accumulate in parking lots of large delivery truck bays or heavy equipment garages. Some gas loggers are more suited for residential use, measuring oxygen and carbon dioxide concentrations. In many models, an alarm will set off if the level of these gases are reached, alerting everyone in the areas.
Geolocation loggers are designed to record the geographic location of an object or animal. These loggers need to be small and lightweight so they can easily be attached to the object or animal being tracked. Earlier models would only have limited storage for data, as well as limited battery life. But technological advancements in both areas have since improved these capacities, making it possible for these devices to record and store data for longer periods of time.
Light level geolocators use primarily light level data, as well as other parameters such as temperature and water immersion, to record its location. Recorded light level data overtime is used to determine the latitude and longitude of the locator. Common application of this type of geolocation loggers is with bird migration to monitor the areas that migratory birds used during migration. Most models store their data in internal memory that can be collected for analysis.
GPS loggers are another type of geolocation loggers and are more accurate than light level geolocators because they use satellite technology to determine their geographical location. GPS loggers are generally larger than light level geolocators are used to track people and bigger animals and objects.
GPS loggers are similar to geolocation loggers, except they use satellite technology to determine its exact geographical location. GPS loggers are similar with GPS navigation devices. However, the latter are bigger and used primarily for navigation.
Built-software in some models also facilitate data analysis given that most models are integrated with a feature that exports their data to a spreadsheet when uploaded to a computer. Most models are bundled with data analysis software for additional analyzing tools and features. Some models store their data in readable SD cards that can be collected for analysis.
GPS loggers are often used to track the movements of animals and people. Continuous satellite data are recorded over time. GPS loggers can accurate track location, the routes taken, stop and start times of movement.
The primary applications of GPS loggers are with military, police and homeland security. They can also be used to track the movements of bigger animals such as herding animals and endangered species such as tigers and elephants.
Humidity loggers are data loggers designed to measure ad record continuous, relative humidity measurements. Most humidity loggers can also measure temperature and dew point (the temperature at which water vapour present in the air begins to condense). Other models even have optional features to expand its capability to measure temperature and humidity by having extra nodes for additional measurement probes. Models that can use probes can extend their measurement range for both humidity and temperature compared to other models.
Software in some models also facilitate data analysis given that most models are integrated with a feature that exports their data to a spreadsheet when uploaded to a computer. Most models are bundled with data analysis software for additional analyzing tools and features. In most cases, data are transmitted wirelessly. Some models store their data in readable SD cards that can be collected for analysis.
These additional features makes many humidity data logger models multi-purpose equipment that can be used for a wide variety of purposes such as in agriculture, the storage and logistics industry, humidors, and in the home.
Light loggers are specifically designed to monitor indoor light changes. Using light sensors, light loggers monitors and records when an indoor light source is turned on, how long the light was on, and the time it was turned off. Most light loggers also have the added feature of determining room occupancy, and how often the room us used. This data is stored within the instrument and then retrieved using its software installed in a computer.
Software in some models also facilitate data analysis given that most models are integrated with a feature that exports their data to a spreadsheet when uploaded to a computer. Most models are bundled with data analysis software for additional analyzing tools and features.
Light loggers are mainly used for energy consumption and to determine room occupancy patterns. Rooms are compared based on how long their light sources where turned depending on whether there was someone in the room. These measurements are needed to comply with existing state regulations about electrical consumption, and can be used to identify areas or rooms where possible savings can be made.
Multi-channel data loggers provide multiple measurements, meaning they record more than one measurement of a single event or measure. This type of data loggers accomplish this by using more than one channel to make their measurement.
Functionally, a multichannel logger is like using more than one data logger at the same time. A good example of a multi-channel data loggers are thermocouple data loggers that need to make different readings using the different thermocouple types such as the ICBTM-4208SD. This model can have 12 channels available to make measurements, allowing it to make different temperature readings using the different types of thermocouples available to it. Similar when 12 different data loggers are used.
Software in some models also facilitate data analysis given that most models are integrated with a feature that exports their data to a spreadsheet when uploaded to a computer. Most models are bundled with data analysis software for additional analyzing tools and features. Some models store their data in readable SD cards that can be collected for analysis.
The advantage of using multi-channel loggers is that using them avoids making use of additional data loggers for different units of measurements. There is no more need to convert measurements to different units when multi-channel data loggers are used and if you need to record on many channels it can be a more cost effective option than using multiple loggers.
Pasteurization loggers are designed exclusively for the food processing and beverage industry, especially with the pasteurization, production and packing of milk and other products that contain it. Pasteurization loggers are designed to have a higher operating temperature compared to other similar data loggers and have a specified measurement range based on the required pasteurization guidelines set by the state.
Built-software in some models also facilitate data analysis given that most models are integrated with a feature that exports their data to a spreadsheet when uploaded to a computer. Most models are bundled with data analysis software for additional analyzing tools and features. Some models store their data in readable SD cards that can be collected for analysis. Bundled software allows the user to also calculate pressure data, pasteurization unit and carbon dioxide values.
Data loggers designed to monitor, measure and record pH are basically pH meters that have the added feature of storing and logging pH measurements. The different types of pH meters also apply to pH loggers. These are portable, bench and in-line pH meters.
Portable pH loggers are hand held devices that are suitable for applications performed outside laboratories or other controlled areas. This type of pH loggers are primarily used in indoor pH monitoring outside of laboratories and for other general purposes. This type of pH logger is the most versatile and most convenient to use. However, portable pH loggers are often less sensitive than bench pH loggers and are less durable compared to in-line pH loggers.
Bench pH loggers are primarily used in research and laboratories. These devices are primarily secured onto tabletops or counters in laboratories. This type of pH loggers are the most advanced and the most sensitive of the three types. However, they are often the most expensive and not practical to use for general applications. Bench pH loggers are often bigger and heavier compared to the other two types, further limiting their use outside of research and laboratories.
The final type is in-line pH meters that are generally used in process control like in water treatment plants, food and beverage production, and in manufacturing. This type of pH loggers are often parts of a continuous monitoring system that not only stores pH measurements, but also to initiate automatic responses within the control systems. This type of pH logger is generally the most durable since they are often left on for continuous monitoring and are generally used in harsher environments. This type of pH logger is also the most limited in use since they have no other applications outside process control systems.
Power loggers are designed to monitor and record power consumption. These devices commonly record Power Factor (PF), Reactive Power (VAR), Watt Hours (Wh) and other parameters. Power loggers also have the capacity to accept high voltage ranges and current, making them flexible devices that can be used in many types of power supply configurations.
The primary application is to measure power consumption. Power loggers are connected directly to power where they can show, real time, how much power is consumed as well as other measures set by the user. Power loggers are generally more sophisticated compared to other data loggers, especially for monitoring purposes that involve high voltage recording. This type of logger also requires more time to set-up given that these devices are more complicated than simpler devices primarily for routine work. Power loggers are also bigger, takes up more space, and are not generally left alone on the field. However, the additional information and the higher load capacity offsets these often minor nuances, especially when accurate monitoring is needed.
Pressure loggers can either refer to barometric pressure loggers which is the atmospheric pressure, or to general use pressure loggers that can be used to other areas. This type of data logger is designed to monitor changes within the pressure found in the area they are used. Barometric pressure loggers monitor the atmosphere, while general pressure loggers can be used in pipes, ovens, gas chambers and other vessels where gases pass through.
Changes in atmospheric pressure can create short-term changes to the weather, making atmospheric pressure loggers valuable tools in monitoring weather changes in a specific place or area. Pressure loggers are generally used in home and professional weather stations that also monitors other weather conditions. Pressure loggers used for this purpose are made of heavy duty and sturdy materials and are water proof to withstand being exposed to outdoor conditions.
Other pressure loggers are often used in more varied situations compared to weather pressure loggers. Aside from being as sturdy as their barometric counterparts, these pressure loggers can withstand higher temperatures and can be submerged into deep water since they are used in different environments. Additional features such as a LCD panel are often included when constant monitoring are required. Common applications include laboratory use such autoclave calibration and monitoring pressurized processes.
Pulse loggers are designed to record the number of times an event has occurred within a given time interval. Pulse loggers are similar with event loggers, but the former are better equipped to record events that happen repeatedly and rapidly within a short amount of time. Pulse loggers are able to do this by generating a pulse for each time an event occurs. Unlike event and state loggers, events recorded by pulse loggers are not time-stamped, since similar events or pulses that occur together are grouped and recorded together within the time period they occurred.
Because pulse loggers record events within a time period, the initial action that triggers a signal must a certain amount of time before it is recorded. Most models would require a signal to last at least 10 microseconds and have at least 100 microseconds between the each recorded pulse for the events to be recorded.
A common application of pulse loggers is to measure the flow rate of liquid in a pipe. The pulse logger is connected to a flow meter and then records pulses based on the information transmitted by the flow meter, making it possible to calculate flow rate and volume.
Unlike other loggers, data from pulse loggers are often not easily transferrable to a spreadsheet file, requiring other software programs to use properly.
Shock loggers are data loggers that autonomously monitor and record vibrations, shakes, impact, jolts or any other sudden form of movement. Shock loggers are primarily used to monitor shipments in transit, especially in cargo trucks and airplanes. These instruments allow distributers and manufacturers to monitor transit goods to ensure that they are transported under ideal conditions. Shock loggers record when any of the described movements occur, recording its time of occurrence, date and in some models, the duration of the recorded movement.
There are different types of shock loggers available based on additional features depending on the need of the manufacturers and the degree of movement they can measure. Some shock loggers can measure temperature and humidity for sensitive items that need to be transported under strict environmental conditions. Other shock loggers can also measure pressure levels for items that need to be transported in vacuum containers such as certain food products and raw materials. Other features include additional functions for measuring strain, moisture and acceleration.
Majority of shock loggers are able to monitor movement using the 3 axis measurement. Under this system, any form of movement such as vibration and jolts are measure based on how much they move the object from three observed plots on a grid (x,y,z). More complex shock loggers can measure movement across six axes, also measuring roll, pitch and yaw in addition to the three basic axes.
Soil moisture loggers are instruments that record the amount of water absorbed in the soil. Measuring soil moisture is significant given that overwatering of the soil can drown root crop systems, dilute the soil of nutrients, lowers the temperature of the soil and cause water logging and promotes salt build up in the root zone. Likewise, soil that doesn’t hold enough water would not allow plants to grow at all and would alter the texture and composition of the soil. These instruments are primarily used by farmers, specifically, on designing and monitoring irrigation systems for their crops.
A disadvantage of using soil moisture loggers is that it can only use a finite number of sensors, making it necessary to acquire more data loggers for larger or uneven plots of land. There is also an issue of managing long lengths of wires from the sensor to the logger itself. Some soil moisture loggers can monitor larger tracts of land compared to others, making it important for the user to research first what type of soil moisture logger can fit with their needs.
Sound level loggers autonomously record differences in sound levels in an area. These measurements are generally based on specific standards for safe human listening. These devices are mainly used to monitor sound levels in manufacturing plants, heavy machines and factories to ensure the safety of the people working in these places. These machines can also be used in engineering and construction.
Sound level loggers work by using the decibel scale to measure the energy consumed to generate noise. The decibel scale is a logarithmic scale, meaning that sounds that go up in decibels are ten times louder than the precious decibel reading. Sounds within a specific range (85dB and above -) are considered unsafe and can damage human hearing. A vital factor measured by sound level loggers is the duration of exposure to a specific sound level to identify areas of concern within an area. These makes the periodic measurement and data logging of sound level loggers more valuable than normal sound level meters.
High quality sound level loggers comply with international standards (IEC 60651, IEC 60804 and ANSI S1.4) and are given various grade types (0-3). The best sound level loggers have a grade of 0. These instruments are the most accurate and the most sensitive and are mostly used in research and laboratories. The most basic models are generally given a grade of 3 and are the least accurate and sensitive. Sound level loggers with a grade of 2 are somewhere in between the two grades and is for general use. Sound level loggers of this grade is the most ideal since they are not as expensive as grade 03 sound loggers, comply with international standards, and are accurate enough to perform general sound level monitoring.
State loggers are similar to event and pulse loggers since all of these models record specific events when they occur. The difference with state loggers is that the events they specifically record events that have ‘on’ and ‘off’ or ‘open’ or ‘close’ states. In most cases, using this specific designation, somewhat limits a state logger’s utility. However, as with pulse loggers, state loggers are the best instruments available in recording these on/off states and should be considered if this type of events are being monitored. Some varieties are programmed to record ‘time of use’ states and their duration which works similarly on how specific types of machinery and equipment are monitored.
Common applications of state loggers are monitoring the usage of electric light sources, initiating or using specific functions in machinery or any other similar events, room occupancy analysis, tracking the use of pumps and motors, the opening of lids or doorways such as the man holes, telephone line switches, and local traffic control panels.
Strain loggers or bridge strain loggers autonomously monitor the strain on different types of architecture such as buildings and bridges. Generally, strain loggers wirelessly send out periodic strain measurements for safety monitoring purposes.
For bridges, the challenge is to create a circuit that connects multiple strain sensors or gauges to strain loggers to cover identified pressure points on the bridge. There are cases where multiple strain loggers are required, requiring a separate circuit to be made for each strain logger. As an example, for one-fourth bridges, a strain logger can be connected to a strain gauge and either a precision bridge completion resistor or a temperature gauge to complete the circuit. The additional components are required to facilitate the conversion of voltage to the desired measurement unit for more accurate measurements. For buildings, the same approach is also used but is applied on a vertical scale.
Temperature loggers are instruments that autonomously measure or record temperature readings within a specific period of time. Temperature loggers is actually a general term used to described more specific types of temperature data loggers such as thermocouple temperature loggers and high temperature data loggers.
Most temperature logger models have built-in thermistors or thermocouples so they can measure temperature on their own. Other models have no such features and needs to be connected to a sensor to have temperature measurements to log. Some models have a digital display to facilitate monitoring, while other have not. Almost all models store their information in internal memory and needs to be connected directly to a computer for further analysis. More complex models transmit their data wirelessly for real time monitoring. Often, temperature loggers also combine other measurement function such as pressure and humidity, increasing their utility.
Given the wide variety of temperature loggers available, it is integral that the user chooses the most appropriate type for the specified monitoring need. Aside from the measurement range, other factors that need to be considered when buying a temperature logger are cost, battery life, ease of use, measurement range, environmental resistance (water/heat/pressure), calibration features and certification.
Thermocouple data loggers are a specific type of temperature loggers that measure and record temperature through the use of a thermocouple. A thermocouple measures temperature by comparing the differences with the temperature sensor with an adjoined conductor inside the instrument. The difference in temperature between the two conductors creates an electrical current that is then measured by a voltmeter and then converted to a temperature reading.
There are different types of thermocouples depending on measurement range and sensitivity. The most appropriate for general use is the type-k thermocouple because it is largely inexpensive and has a wide measurement range. Many multi-purpose temperature loggers use a type k thermocouple and is mostly the most available model for general use thermocouple data loggers.
USB stick loggers are data loggers with a built-in USB port to facilitate data transfer. USB stick loggers generally run a specific interface program that allows data to be directly imported from the instrument to a computer. Some models can directly export their data directly into a spreadsheet, while some would still additional software to read the stored data.
Many types of data loggers have USB stick variations. This is mostly the result of this type’s popularity to consumers because of the ease of transferring data to a computer. The most common type of data loggers to have a USB variant are temperature, humidity, voltage and pressure loggers.
Voltage data loggers autonomously monitor, record AC/DC voltage readings and statistics. Voltage loggers are used widely in many industries that include manufacturing, energy distribution and generation, food processing, logistic delivery services and others.
Voltage loggers function similarly with volt meters but can continuously measure and record voltage readings within a specified amount of time. Some models need to be connected to voltage probes to function and needs to be installed together with other instruments. Many voltage loggers can also measure other parameters such as humidity, pressure and temperature.
Weather loggers are often used together with other weather instruments to record various measurements. Most weather stations have built-in weather data loggers or are compatible with data loggers of the same brand. In most cases, the specifications of the weather logger should fit with the other instruments it will be used together with, as well as the location where the weather logger will be placed.
Because of its purpose, weather loggers are more durable compared to other data loggers. Weather loggers are generally weather proof and can withstand changes in weather and temperature. Their casing are made of heavy-duty material and would not ideally bend or break easily even. Many weather loggers have wireless capability, allowing them to transmit their data without needing to setup wires. In most cases, the receiver is portable and hand held, for easy reading. Some models have no such capability.
Wireless data loggers are a type of data loggers that can send real-time measurements through the internet to a remote receiver. For many types of data loggers, this feature is a boon in situations where it is difficult to place wires to connect the data logger to a receiver, making this feature more significant in difficult to manage areas that require continuous monitoring and updates. Compared to the other types of data loggers, this is the only type reliant on the internet to truly function.
A common trait among data loggers is that they all need specific software to allow the user to interpret and analyze their recorded data. Most data loggers would not function without their own software installed in a remote computer station, while other types, such as pulse loggers, are reliant on their own software to make sense of the data they recorded. Only some USB loggers maybe less reliant to software compared to others if they can directly export their data as spreadsheets. While most data loggers would have an installer included in the package, supplemental software may be purchased for additional features and functions not present in the main program.
Additional cables are necessary especially in situations where there is a need to connect multiple sensors to a single data logger where multi-channel data loggers are unavailable. Data cables are also needed when connecting a data logger to another set of instruments for monitoring. Additional cables may also become needed when connecting the data loggers to cover a larger area such as soil moisture data loggers. Specialized cables are also needed in some models that needs the data logger to be connected directly to a computer.
Different data logger models would require different accessories, mainly because of additional options that a user can purchase. Additional protective cases for USB type loggers generally are not included with the purchase of the product. Power adapters may be bought to avoid using batteries for majority of data loggers. Likewise, more expensive, rechargeable Lithium ion batteries can also be purchased. Some outdoor data loggers have compatible solar panels available in situations where it may be difficult to constantly replace batteries.
While model-specific accessories may vary, measurement probes are vital for all data loggers and is often the most widely purchased accessory for them. Different sensor probes are available depending on what type of function is being measured. In some models, additional sensors can further expand the features of the data logger, greatly increasing and expanding its utility. In some applications, buying large amounts of sensor probes are necessary, especially in situations where they may get lost or damaged. Stands, protective guards and platforms are often needed for outdoor data loggers for easy placement and convenience.
