Holosys Wireless M-Bus OMS Temperature Sensor WTS

Holosys Wireless M-Bus OMS Temperature Sensor WTS is a device that provides wireless temperature measurement via radio telegrams according to the Wireless M-Bus OMS standard.

 

The device is equipped with temperature sensor probe on a cable and provides accurate environment temperature measurement (±0.5°C accuracy in -10°C ... +85°C temperature range).

 

Besides temperature, it can optionally read two digital inputs (CH1 and CH2) states. The Wireless M-Bus OMS communication protocol ensures compatibility with a wide range of the equipment.
