HYGRASGARD® DFF-I

The calibratable humidity and temperature sensor HYGRASGARD® DFF / DFTF measures the relative humidity and temperature of the air. It converts the measured variables 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 (in % RH) is the quotient of the water vapor partial pressure and the saturation vapor pressure at the respective gas temperature. The measuring transducer is designed for the exact recording 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 recessed ceiling sensor is used in non-aggressive, dust-free environments and is used for installation in false ceilings in corridors, offices, residential and commercial premises. The connection head is pluggable for quick and easy installation. The measuring transducer is located in a separate housing.
