RPFF-SD-I 4...20mA Pendulum room sensor RV active (vh RPFF-LC)

The calibratable humidity sensor HYGRASGARD~ RPFF-LC, with plastic sinter filter measures relative humidity. Is used in building automation, cooling, heating, ventilation and clean room technology in greenhouses and halls. Converts the measured variables into a standard signal of 4...20 mA. The relative humidity (in % r. H.) is the quoti~nt of the water vapor parti~le pressure and the saturation vapor pressure at the prevailing gas temperature. A capacitive sensor is used as the measuring element for humidity measurement, a digital sensor with long-term stability as the measuring element for moisture measurement. Fine adjustment by the user is possible. The sensor is suitable for installation in ducts and devices.
