The calibrateable duct humidity and temperature sensor HYGRASGARD® KFTF, accuracy class ± 3 % r.H., measures the relative humidity and temperature of air. It converts the measurands humidity and temperature into standard signals of 0 – 10 V or 4...20 mA and is optional available with or without display, with terminal box enclosure made of impact-resistant plastic, enclosure cover with quick-locking screws. . It is used in non-aggressive dust-free ambiences in refrigeration, air conditioning, ventilation and clean room technology. Relative humidity (in % r.H.) is the quotient of water vapour partial pressure divided by the saturation vapour pressure at the respective gas temperature. These measuring transducers are designed for exact detection of humidity. A digital long-term stable sensor is used as measuring element for humidity measurement. Fine adjustment by the user is possible. A mounting flange is included in the scope of delivery.
