The calibratable room humidity and temperature sensor
measures the relative humidity and/or temperature of air. It converts the measurands
humidity and temperature into standard signals of 0 -10 V and is available in an elegant housing made of plastic, with snap-on lid, base with 4-hole
attachment for installation on vertically or horizontally installed in-wall flush boxes, with predetermined breaking point for on-wall cable entry. The
relative humidity (in % r.H.) is the quotient of water vapour partial pressure divided by the saturation vapour pressure at the respective gas tem-
perature.
It is used in non-aggressive dust-free atmospheres in refrigeration, air conditioning, ventilation and clean room technology, in interior rooms such as
residential rooms, offices, hotels, technical rooms, meeting rooms and convention centres. These measuring transducers are designed for exact
detection of air temperature and humidity. A digital long-term stable sensor is used as a measuring element for humidity and temperature measure-
ment. Fine adjustment by the user is possible.
