W0841E Wireless temperature sensor with 4 external Pt1000 probes with CINCH connector, IoT Sigfox

The device measures temperature from 4 external Pt1000 probes on the cable - you can choose it as an optional accessory.

The measured values ​​are sent in an adjustable time interval (10 min to 24 h) by radio transmission from the Sigfox network to the COMET Cloud, from which the user can view the data using a mobile device or a computer.

The device can monitor up to 2 alarm limits for each temperature channel. When these limits are exceeded the device sends an emergency message. The COMET Cloud transmits this alarm via e-mail to the corresponding user. This device is suitable for tasks that tolerate the delay of information provided by Sigfox (max. 10min).
