W0854P Wireless Thermometer with Built-in Sensor and with Pulse Counting 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. The sensor also has a reading input that can be connected to all energy meters with pulse output. When connected to a suitable sensor on the production line, it can, for example, count the number of pieces produced or be used to measure the average frequency of the input pulses (e.g., to measure wind speed when the input is connected to an anemometer).

The measured values ​​are sent at an adjustable time interval (from 10 minutes to 24 hours) by radio transmission via 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 according to EN ISO/IEC 17025
