HYGRASGARD® AFF-20-I （LCD）Calibratable HYGRASGARD® AFTF/AFF (± 2,0%) and AFTF - 20/ AFTF-20 (± 1,8%) outside humidity/temperature transmitters with plastic sinter filter (metal sinter filter optional) orAFTF - 25/ AFTF-25 (± 1,8%) with pluggable measuring head and metal sinter filter; 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 measuring transducers measure the relative humidity and/or temperature of the air 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. 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 devices are factory-calibrated and can be fine-tuned to ambient conditions by an expert.
