Description

Pendulum room humidity sensor HYGRASGARD® RPFF-SD
The calibratable HYGRASGARD® RPFF - SD pendulum humidity transmitter with plastic sinter filter measures the relative humidity of the air. It converts the measurand 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.
The measuring transducer is used in non-aggressive, dust-free environments, in refrigeration, air conditioning and cleanroom engineering, hotels, engineering rooms, meeting and conference facilities. It provides precise detection of humidity. A digital long-term stable sensor is used as measuring element for humidity. The sensor is suitable for duct installation, as a pendulum sensor, or for integration in equipment.
