The WTX-275-EXT is a state of the art 915 MHz wireless temperature transmitter with extended range due to its external antenna. It has been designed for a wide range of applications especially in the food industry. It has been designed to go directly into fridges and freezers as well as having an external jack plug to accept Pt100 sensors.
It can be deployed adjacent to the point of measurement where this is required, such as measuring tank temperatures and the temperature of water in pipes.
The external antenna will increase the signal transmission strength by about 6dB, providing improved signal strength at the gateway and thus improving its range. It is intended for applications where it is likely the signal strength received at the gateway will be around -100 dBm to -110 dBm without the external antenna. It will improve the signal to around -93dBm to -103dBm, this extending the range substantially.
Features:
- Mounts directly into fridges and freezers using internal Class B (+/- 0.3oC) Pt100 sensor.
- Solid construction, suitable for fridges and freezers.
- The WTX-275-EXT mounts in a WTX-RCP magnetic receptacle.
- Very easy to deploy. No tools required.
- Powered by Lithium AAA batteries suitable for freezer temperatures.
- No interruption to work area when deploying these transmitters.
- External jack-plug to accept externally mounted 3 wire Pt100 sensors.
- Internal dipole antenna.
- Works with all GW-100 gateways.
- Distance in building interior: up to 100m.
- Distance in open line of sight: up to 500m.
- Up to 120 WTX series transmitters can operate with one GW100 series gateway.
- Increases the signal transmission strength by about 6dB, providing improved signal strength at the gateway and thus improving its rang
- Increases the signal transmission strength by about 6dB, providing improved signal strength at the gateway and thus improving its rang
