The calibrateable room humidity and temperature sensor HYGRASGARD® RFTF-U-x measures the relative humidity and temperature of air. It converts the measurands humidity into standard signals of 0 – 10 V or 4...20 mA and temperature into a passive resistor output. . These sensors are optional available with or without display (displaying actual humidity and actual temperature), in plastic or stainless steel enclosures. Relative humidity (in % r.H.) is the quotient of water vapour partial pressure divided by the saturation vapour pressure at the respective gas temperature. HYGRASGARD® RFTF-U-x is applied in non-aggressive dust-free ambiences in refrigeration, air conditioning and clean room technology, in indoor rooms, like living rooms, offices, hotels, technical rooms, meeting rooms and convention centres. These measuring transducers are designed for exact detection of humidity and temperature . A digital long-term stable sensor is used as measuring element for humidity measurement. Fine adjustment by the user is possible.
