HYGRASGARD
The humidity ⁄ temperature sensor HYGRASGARD
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. HYGRASGARD
RFTF-UP are applied in non-aggressive dust-free ambiences 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 measuring element for humidity and
temperature measure ment.
