HYGRASGARD® KFF-I （LCD）Calibratable HYGR ASGARD® KFF / KFTF or KFF - 20 / KFTF - 20 duct humidity/temperature transmitters (±2.0% or ±1.8%, respectively) with plastic sinter filter (metal sinter filter optional),housing made of impact resistant plastic, housing cover with quick-locking screws, with/without optional display The sensor devices measure relative humidity and/or air temperature and convert the measurand into a standard signal of 0-10 V or 4...20 mA. The 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 is factory-calibrated and can be fine-tuned to ambient conditions by an expert.
