HYGRASGARD
Quality product for HVAC sector, accuracy 3 % r. H.
The calibrateable pendulum room humidity sensor HYGRASGARD
converts the measurand humidity into a standard signal of 4 ... 20 mA. 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
ambiences in refrigeration, air conditioning, ventilation and clean room technology, hotels, technical rooms, meeting rooms and convention centres.
These measuring transducers are designed for exact detection of humidity. A digital long-term stable sensor is used as measuring element for
humidity measurement. This sensor is applicable for duct installation, as pendulum feeler, or for integrating it into equipment.
