HYGRASGARD® AFF-20-U LCD

Calibratable outdoor humidity/temperature sensor HYGRASGARD® AFF-20 / AFTF-20 (± 1.8 %) with plastic sintered filter (optional metal sintered filter), housing made of impact-resistant plastic with quick-locking screws, optionally with/without display and with cable gland (optional M12 plug connector to DIN EN 61076-2-101).

The devices measure the relative humidity and/or temperature of the air and convert the measured variable into a standard signal of 0-10 V or 4...20 mA. It has four switchable temperature ranges and is used in non-aggressive, dust-free environments, in refrigeration, air conditioning, ventilation and clean room technology. The transmitters are designed for the precise measurement of humidity. A digital, long-term stable sensor is used as the humidity measuring element. The sensor is calibrated at the factory; fine adjustment by a specialist is possible depending on the environment.
