Description

The transmitter measures the temperature of three external K-type thermocouple probes (NiCr-Ni) and the ambient temperature using an integrated sensor.

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

The instrument can monitor up to 2 alarm limits for each measured temperature channel. Exceeding these limits is indicated by sending an emergency message. COMET Cloud transmits this alarm message by email to the selected user. The device is suitable for applications that tolerate the delay of the information delivered by Sigfox (maximum 10 min).

Highlighted features:

  • Wireless transmission of measured values ​​and alarm states
  • Temperature measurement at up to four locations for the price of one subscription
  • Battery powered (size C 3.6 V) with low battery indication (battery life up to 10 years)
  • Remote configuration of the device from the COMET Cloud (maximum once per day)
  • IP65 for use of the device in external applications
  • Traceable calibration certificate according to EN ISO/IEC 17025
