Measure ambient temperature from -40 to +80 degrees Celsius and transmit it wirelessly to a central wireless receiver for distributing to other instrumentation via analogue output, digital coms, or a mobile network.
Product Features
- Measures ambient temperature
- 0.5°C accuracy
- -20 to +80°C measurement range
- Up to 500 m line-of-site range (depending on receiver)
- User-selectable transmission update rates
- Analog output, RS-232/485, Ethernet, USB, cellular network receivers
Product Description
The IWTaT wireless ambient temperature sensor is battery powered and can be installed up to 500m away from the wireless receiver unit.
Monitor and log the local temperature in multiple locations using the user interface dashboard provided for each type of wireless receiver.
Each wireless ambient temperature sensor is compatible with a choice of wireless receivers to transmit the temperature readings via an analogue output, Ethernet TCP connection, RS232/RS485 Modbus RTU serial interface, or a 2G/3G/4G mobile cellular network.
