HYGRASGARD
Quality product for HVAC sector, accuracy 3 % r.H.
The calibrateable pendulum room humidity and temperature sensor HYGRASGARD
humidity and temperature of air. It converts the measurands humidity and temperature into standard signals of 0 - 10 V or 4...20 mA and
is optional available with or without display. It has four switchable temperature ranges. 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
in non-aggressive dust-free 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 temperature and humidity.
A digital long-term stable sensor is used as measuring element for humidity and temperature measurement. Fine adjustment by the user
is possible. The sensor is appropriate for ceiling and duct installation, or for integrating it into equipment.
