HYGRASGARD® VFF-U

The calibratable humidity and temperature transmitter HYGRASGARD® VFF/VFTF measures the relative humidity and temperature of the air. It converts the measured variables humidity and temperature into a standard signal of 0-10 V or 4...20 mA and is optionally available with⁄without display. It has four switchable temperature ranges. The relative humidity (% RH) is the quotient of the water vapor partial pressure and the saturation vapor pressure at the respective gas temperature. The transmitters are designed for the precise measurement of temperature and humidity. A digital, long-term stable sensor is used as the measuring element for humidity and temperature. The sensor is calibrated at the factory; fine adjustment by a specialist is possible depending on the environment.

The display case sensor is used in non-aggressive, dust-free environments and is particularly suitable for installation in ceilings, walls, display cases or showcases in museums, galleries, cinemas, auditoriums or laboratories. The measuring element is located in a stainless steel probe and is hardly noticeable due to its very low height (approx. 2.5 mm).
