AFF-25-U 0-10V Outdoor sensor RV active with pluggable measuring head TYR II

The calibratable outdoor ~ duct humidity and temperature sensor HYGRASGARD~ KFF-20 / KFTF-20 respectively AFF-20 / AFTF-20 / AFF-25 / AFTF-25 is a robust industrial variant, equipped with metal sinter filter. It measures the relative humidity and / or temperature of the air. It converts the measured values into a standard signal 0-10V or 4-20mA and is optionally available with display (for displaying the actual temperature or humidity). In impact-resistant plastic housing with quick-release screws. It features four switchable temperature ranges. These transducers find their application in non-aggressive, dust-free environments, in cold, climatic, and clean rooms, in ventilation and air conditioning plant ducts for the humidification and dehumidification of industrial halls, offices, hotels, conference rooms and technology rooms. The relative humidity (in % r. H.) is the quoti~nt of the water vapor partial pressure and the saturation vapor pressure at the prevailing gas temperature. The transmitters are intended for precision measurement of temperature and humidity. A digital sensor with long-term stability is used as the measuring element for humidity and temperature measurement. Fine adjustment by the user is possible.
