The calibratable humidity and temperature sensor RFTF measures the relative humidity and temperature of the air. It converts the measured values into a standard signal 0-10V. In design housing made of plastic, with snap cover and in the bottom 4 slotted holes for mounting on a flush-mounting box. The relative humidity (in % r. H.) is the quotient of the water vapor partial pressure and the saturation vapor pressure at the prevailing gas temperature. The HYGRASGARD® RFTF is used in non-aggressive, dust-free environments, in cold, air-conditioning, and clean rooms, in indoor areas such as homes, offices, hotels, technical rooms, meeting rooms, and conference centers. 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.
It is optionally available with display (for displaying actual temperature or humidity). Optionally also available in stainless steel housing (top and bottom are made of stainless steel, the lid is screwed on), vandal-resistant version for schools, barracks and public buildings, as well as where stainless steel fits better in the office interior.
