HYGRASGARD® KFF-20-I (LCD)Calibratable HYGRASGARD® KFF - SD / KFTF - SD duct humidity/temperature transmitters (± 2,0%), with plastic sinter filter (metal sinter filter optional), housing made of impact resistant plastic with snap-on cover, with cable gland (or optional M12 connector according to DIN EN 61076-2-101). Calibratable HYGRASGARD® 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 with quick-locking screws, optionally with/without display, with cable gland (or optional M12 connector according to DIN EN 61076-2-101). The sensor devices measure relative humidity and/or air temperature 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. 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.
