W0870P Wireless Thermometer with built-in Sensor and with Voltage input, IoT Sigfox

The device measures temperature using an integrated sensor and can be installed directly in the measured space thanks to its IP65 protection and DC voltage in the range of -30 to +30 V. By measuring the DC voltage, it is possible to remotely monitor, for example, the battery status or, in general, the power status of the monitored system. The input also allows the connection of sensors of various magnitudes with a standard output, for example, from 0 to 10 V.

The measured values ​​are sent at an adjustable time interval (from 10 minutes to 24 hours) by radio transmission through the Sigfox network to COMET Cloud, where the user can view them from a computer or mobile device.

The instrument can monitor up to two alarm limits for the measured variable. If these limits are exceeded, an emergency message is sent. COMET Cloud sends this alarm message by email to the selected user. The device is suitable for applications that tolerate the delay in information provided by Sigfox (max. 10 minutes).

Highlighted features:

Wireless transmission of measured values ​​and alarm statuses
Battery-powered (battery life 1 to 10 years)
LED indication of device status
Remote device configuration from COMET Cloud (maximum once per day)
IP65
Calibration certificate traceable to EN ISO/IEC 17025
