The humidity ⁄ temperature sensor HYGR ASGARD
®
RFF-UP ⁄ RFTF-UP measures
the relative humidity and ⁄ or temperature of air. It converts the measurands humidity
and temperature into standard signals of 0 -10 V. Relative humidity (in % r. H.) is the
quotient of water vapour partial pressure divided by the saturation vapour pressure
at the respective gas temperature.
RFF-UP
⁄ RFTF-UP are applied in non-aggressive dust-free atmospheres in
refrigeration, air conditioning, ventilation and clean room technology, in 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 measurement.
