Description
Duct humidity sensor for mixture ratio
HYGRASGARD® KAVTF
The universal HYGRASGARD® KAVTF humidity measuring transducer with 6 output values is used to determine diverse measurands in humidity measuring. Measurands include relative humidity and ambient air temperature. These measurands are used to calculate various parametres internally.
The transmitters have been designed to operate in pollutant-free, non-precipitating air with neither above-atmospheric nor below-atmospheric pressure at the sensors. Application examples include medical, refrigeration, air conditioning and clean room engineering. The sensors are suitable for duct installation.
