Siemens QFM2160 Duct Sensor

Product Id : 157398


Siemens QFM2160 Duct Sensor acquires the relative humidity in the air duct whose electrical capacitance changes as a function of the relative humidity via its capacitive humidity sensing element. This sensor also acquires the temperature in the air duct via its sensing element whose electrical resistance changes as a function of the temperature.

Applications: Air Conditioning and Ventilating Systems, Pharma Labs, Food Processing Industries, HVAC, automobiles, EDP Centers, and Hospitals.
