HYGRASGARD® DFF/DFTF
The calibratable HYGRASGARD® DFF humidity and temperature transmitter 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 optional display.
The measuring transducer supports 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 sensor device provides precise detection of temperature and humidity. A digital, long-term stable sensor is used as a measuring element for humidity and temperature.
