177WD
Air temperature sensor wall mount
The 177WD is an all stainless steel sensor with a cutaway measuring point, and has a rear flange for wall mounting. This sensor is specifically intended for measuring ambient air temperature. Optionally, the sensor can be equipped with a 2-wire transmitter type TRM33A, this only for applications in rooms with a minimum ambient temperature of + 5 ° C. The sensor can also be supplied in a version for measuring Relative Humidity.
