The calibratable humidity and temperature sensor HYGRASGARD® RFF/ RFTF measures the relative humidity and/ or the temperature of the air. It converts the measurands humidity and temperature into a standard signal of 0 – 10 V or 4…20 mA, and is available with or without an optional display (for displaying actual humidity and actual temperature), in an elegant housing made of plastic, with snap-on lid, base with 4-hole attachment for installation on vertically or horizontally installed in-wall flush boxes, with predetermined breaking point for on-wall cable entry, or in an housing made of stainless steel (top and bottom part are of stainless steel, the lid is screwed on), vandal-proof version e.g. for schools, military barracks, and public buildings. Relative humidity (in % r. H.) is the quotient of water vapour partial pressure divided by the saturation vapour pressure at the respective gas temperature.
