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; 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.The sensor is factory-calibrated; an environmental precision adjustment by an expert is possible.
