AFTF-SD-I 2x 4..20mA Outdoor post. RH / temp. adjustable (former AFTF-LC-I)

The calibratable humidity / temperature sensor HYGRASGARD~ KFF / KFTF measures the relative humidity and temperature of the air and of other non-aggressive gases. Used in building automation, refrigeration, air conditioning, ventilation and clean room technology, in greenhouses and halls. Converts the measured values into a standard signal of 0-10V or 4...20 mA. The relative humidity (in % r. H.) is the quoti~nt of the water vapor parti~le pressure and the saturation vapor pressure at the prevailing gas temperature. The measuring transducers are intended for the precision measurement of temperature and humidity. A capacitive sensor is used as the measuring element for humidity measurement. The housing is suitable for wall or duct mounting. The sensor is available with or without display. Fine adjustment by the user is possible.
