The room humidity sensor HYGRASGARD® RFF-UP measures the relative humidity of air. The humidity transmitter converts the measurand humidity into standard signals of 0 – 10 V. This room humidity sensor for the residential environment is applied in non-aggressive dust-free ambiences in refrigeration, air conditioning, ventilation and clean room technology, in residential rooms, offices, hotels, technical rooms, meeting rooms and convention centres. Relative humidity (in % r.H.) is the quotient of water vapour partial pressure divided by the saturation vapour pressure at the respective gas temperature. These measuring transducers are designed for exact detection of humidity. A digital long-term stable sensor is used as measuring element for humidity measurement.
