Item No. 1201-7132-1000-101
EAN 4 251325 611495

Quality product for HVAC sector, accuracy ± 1.8 % or ± 2.0 %

Calibratable outdoor humidity/ temperature sensor HYGRASGARD® AFF/ AFTF (± 2.0 %) and AFF - 20/ AFTF - 20 (± 1.8 %) with plastic sinter filter (optional metal sinter filter) or AFF - 25/ AFTF - 25 (± 1.8 %) with pluggable metal sinter filter; terminal box housing made of impact-resistant plastic, with/ without optional display.

It measures the relative humidity and/ or the temperature of the air and converts the measurand into a standard signal of 0 - 10 V or 4...20 mA. It has four switchable temperature ranges and is applied in non-aggressive dust-free atmospheres in refrigeration, air conditioning, ventilation and clean room technology. Relative humidity (in % r. H.) is the quotient of water vapour partial pressure divided by the saturation vapour pressure at the respective gas temperature. These measuring transducers are designed for exact detection of humidity. A digital long-term stable sensor is used as measuring element for humidity measurement. Fine adjustment by the user is possible.
