HYGRASGARD® KFTF-U NTC10KCalibratable HYGRASGARD® KFTF (± 2,0%) or KFTF - 20 (± 1,8%) duct humidity/temperature transmitter (±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 (optionally with M12 connector according to DIN EN 61076-2-101). The sensor device measures relative humidity and/or air temperature and converts the measurands into a standard signal of 0-10 V or 4...20 mA. It supports four switchable temperature ranges and is applied in non-aggressive dust-free atmospheres in refrigeration, air conditioning, ventilation and cleanroom engineering. The measuring transducer provides 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.
