Description

On-wall humidity and temperature sensor HYGRASGARD® AFTF Calibratable HYGRASGARD® AFF / AFTF outside humidity/temperature transmitter (±2,0%) with plastic sinter filter (metal sinter filter optional) , in an impact resistant plastic housing with quick-locking screws, optionally with/without display, with cable gland (optionally with M12 connector according to DIN EN 61076-2-101). 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. Both humidity/temperature transmitters 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. The 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.
