KFTF-20-U VA （Q）（LCD）Calibratable HYGRASGARD® KFTF - 20-VA humidity and temperature transmitter (± 1.8%) with metal sinter filter, rugged housing in V4A stainless steel, optionally with/without display, with cable gland or M12 connector according to DIN EN 61076-2-101. The sensor device measures relative humidity and air temperature and converts these measurand 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.
