The calibratable pendulum humidity sensor HYGRASGARD® RPFF - SD, with plastic sinter filter measures the relative humidity of the air. It converts the measurands humidity into a standard signal of 4...20 mA. Relative humidity (in % r. H.) is the quotient of water vapour partial pressure divided by the saturation vapour pressure at the respective gas temperature.
It is used in non-aggressive, dust-free environments, in the refrigeration, air conditioning and clean room technology, hotels, engineering rooms, meeting and conference facilities. These measuring transducers are designed for exact detection of humidity. A digital long-term stable sensor is used as measuring element for humidity measurement. The sensor is suitable for duct installation, as a pendulum sensor, or for integration in equipment.
