Surface-mounted humidity and temperature sensors HYGRASGARD® AFF-25-U

Calibratable outdoor humidity/temperature sensor HYGRASGARD® AFF-25 / AFTF-25 (± 1.8 %) with plug-in measuring head, metal sinter filter, housing made of impact-resistant plastic with quick-release screws, optionally with/without display, with cable gland (optional M12 plug connector in accordance with DIN EN 610762101).


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. They have four switchable temperature ranges and are 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.
