Calibratable outdoor humidity ⁄ temperature sensor (± 3 %) or (± 2 %)

It converts the measured humidity and temperature into a standard signal of 0 - 10 V or 4...20 mA, and is available with ⁄ without an optional display. It is equipped with four switchable temperature ranges. Relative humidity (in % r. H.) is the quotient of water vapour partial pressure pided by the saturation vapour pressure at the respective gas temperature.
It is used in non-aggressive, dust-free environments, in the refrigeration, air conditioning and clean room technology, hotels, engineering rooms, meeting and conference facilities. The measuring transducers are designed for exact detection of temperature and humidity. A digital, long-term stable sensor is used as a measuring element for humidity and temperature measurement. Fine adjustment by the user is possible. The sensor is suitable for ceiling and duct installation or for integration in equipment.
