AFTF-20-I Q Display, 4...20mA, ±1, 8%, 5P chassis socket for M12, IP67

Quality product for HVAC applications, accuracy ± 1.8 % c.q. ± 2.0 %

Calibratable outdoor humidity/temperature sensor HYGRASGARD® AFF/ AFTF (± 2.0 % ) and AFF - 20/ AFTF - 20 (± 1.8 %) with plastic sinter filter (optional metal sinter filter) or AFF - 25/ AFTF - 25 (± 1.8 %) with plug-in metal sinter filter; terminal box housing made of impact-resistant plastic, optional with / without display. It measures the relative humidity and/or temperature of the air and converts the measured values 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 relative humidity (in % r.h.) is the quotient of the partial pressure of the water vapor and the saturation vapor pressure at the respective gas temperature. The measuring transducers are intended for precise recording of humidity. A digital, long-term stable sensor is used as the measuring element for humidity measurement. Fine adjustment by the user is possible.
