HYGRASGARD® AFF-20/ AFTF-20 (±1,8%)

The measuring transducers measure the relative humidity and/or temperature of the air and convert the measurands into a standard signal of 0-10 V or 4...20 mA. They support four switchable temperature ranges and are applied in non-aggressive, dust-free atmospheres in refrigeration, air conditioning, ventilation and cleanroom engineering. 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 provide precise detection of humidity. A digital long-term stable sensor is used as measuring element for humidity. The sensor devices are factory-calibrated and can be fine-tuned to ambient conditions by an expert.
