The calibratable room humidity sensor HYGRASGARD® RPFF - SD, with plastic sinter filter measures the relative humidity of the air. It converts the measured variable humidity into a standard signal of 4...20 mA. The relative humidity (in % r.H.) is the quotient of the water vapor partial pressure and the saturation vapor pressure at the respective gas temperature.
The transmitter is used in non-aggressive, dust-free environments, in refrigeration, air conditioning and clean room technology, in hotels, technical rooms, assembly and conference facilities. It is designed for the precise measurement of humidity. A digital, long-term stable sensor is used as the humidity measuring element. The sensor is suitable for duct mounting, as a pendulum sensor or for device installation.
