HYGRASGARD® AFF-SD-I LCD

Product Description

Quality product for HVAC sector, accuracy 2 % RH
The calibratable outdoor humidity ? temperature sensor HYGRASGARD® AFF - SD/ AFTF-SD measures the relative humidity and ? or the temperature of the air. It converts the measurand into a standard signal of 0 - 10 V or 4...20 mA, is available with ? without optional display, with terminal box enclosure made of impact-resistant plastic, enclosure cover with quick-locking screws.
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 % RH) 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.
