HYGRASGARD
Quality product for HVAC sector, accuracy ± 2 % bzw. ± 3 % r. H.
The calibratable pendulum room humidity and temperature sensor HYGRASGARD
RPFF - 25 ⁄ RPFTF - 25 (± 2 %) with pluggable metal sinter filter; measures the relative 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 available with or without an optional 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. The sensor is applied in non-aggressive dust-free atmospheres 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 a 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.
