Relative humidity and temperature sensor PM-V

duct-mount

The PM-V is a capacitive relative humidity and temperature sensor manufactured by Galltec. It is integrated with an hx-processor for measuring humidity through a humidity-dependent condenser. The device is constructed based on thinfilm technology, equipped with a base plate. This plate serves as the case of the electrodes, and features a hygroscopic polymer layer on top. The layer absorbs water molecules from the measuring medium, and can also be released by changing the condenser's capacity.
