RFTF-U NTC 20K Room humidity and temperature sensor (surface mounted) BALDUR II

The calibratable humidity and temperature sensor HYGRASGARD~ RFF / RFTF measures the relative humidity and / or temperature of the air. It converts the measured values into a standard signal 0-10V or 4-20mA. It is optionally available with display (for indication of the actual temperature or humidity). In plastic design housing, with snap cover and 4 slotted holes in the bottom for mounting on a flush-mounting box. 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, but also where stainless steel fits better in the office interior. 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 HYGRASGARD~ RFF / RFTF is applied in non-aggressive, dust-free environments, in cold-, climatic-, and clean rooms, in indoor areas such as homes, offices, hotels, technical rooms, conference rooms, and congress 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.
