The calibrateable pendulum room humidity sensor HYGRASGARD® RPFF measures the relative humidity of air. It converts the measurand humidity into standard signals of 0 – 10 V or 4...20 mA and is optional available with or without display. It is used in non-aggressive dust-free ambiences in refrigeration, air conditioning, ventilation and clean room technology, in 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. Fine adjustment by the user is possible. This sensor is appropriate for ceiling or duct installation as well as for integrating it in devices.
