HRT250 humidity transmitter is intended for wall/ room-mounting in HVAC-applications, swimming baths, greenhouses,stables etc. The humidity transmitter has a capacitive thin-film element which gives a signal that is proportional to the relative humidity. The measuring signal is converted by the built-in electronics to output signals, 0 - 10 V or 4-20mA

Measuring element
The transmitter has an accuracy of +/- 2%RH (0...90%RH), +/-3% (90...100%RH). The measuring element has rapid response to changes in humidity. It can withstand saturation without negative effects on the accuracy. The sensor element can be subjected to 100 %RH without being damaged and has excellent long-term stability. The element also has good durability in contaminated environments.
