Ceiling built-in humidity sensors
HYGRASGARD® DFF

HYGRASGARD® DFF

The calibratable humidity and temperature sensor HYGRASGARD® DFF measures the relative humidity and temperature of air. It converts the measurands into a standard signal of 0 - 10 V or 4...20 mA, and is available with/ without an optional display.
It is equipped with four switchable temperature ranges. Relative humidity (in % r.H.) is the quotient of water vapour partial pressure divided by the saturation vapour pressure at the respective gas temperature. The measuring transducers are designed for exact detection of temperature and humidity. A digital, long-term stable sensor is used as a measuring element for humidity and temperature measurement. The sensor is factory-calibrated; an environmental precision adjustment by an expert is possible.

The ceiling-installed sensor is used in non-aggressive, dust-free environments and is used for installation in suspended ceilings in corridors, offices, as well as in residential and commercial buildings. The connecting head is pluggable for quick, easy mounting. The measuring transducer is accommodated in a separate housing.
