HYGR
Calibratable duct humidity/ temperature sensor HYGR ASGARD® KFF/ KFTF (± 2.0 %) or KFF - 20/ KFTF - 20 (± 1.8 %), with plastic sinter filter (optional metal sinter filter),housing made from impact-resistant plastic, housing cover with quick-locking screws, 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.
