RPFF-I 4...20mA, 2m cable, Pendulum room sensor RV active (standard)

The calibratable humidity/temperature sensor HYGRASGARD~ RPFTF, with plastic filter measures the relative humidity and temperature of the air and other non-aggressive gases. Application is in building automation, cooling, heating, ventilation and clean room technology in greenhouses and halls. Converts measured values into a standard signal of 0-10V or 4...20 mA and is available with or without display. The HYGRASGARD~ RPFTF version has four switchable temperature ranges. 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. The measuring transducers are intended for precision measurement of temperature and humidity. A capacitive sensor is used as the measuring element for humidity measurement. A digital sensor with long-term stability is used as the measuring element for humidity and temperature measurement. Fine adjustment by the user is possible. The sensor is suitable for installation in ceilings, ducts and devices.
