HYGRASGARD® AFTF-SD-I

Item No. 1201-1122-1000-100
EAN 4 251325 610023

Quality product for HVAC sector, accuracy 3 % r.H.
The calibratable outdoor humidity/ temperature sensor HYGRASGARD® 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 housing made of impact-resistant plastic, housing 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 % 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.
