HYGRASGARD® KFF-SD-I

Item No. 1201-3182-0000-029
EAN 4 251325 610580

Quality product for HVAC sector, accuracy ± 2.0 %

Calibratable duct humidity ⁄ temperature sensors HYGRASGARD® KFF - SD, with plastic sinter filter (optional metal sinter filter), terminal box enclosure made of impact-resistant plastic, enclosure with snap-on lid. It measures the relative humidity and ⁄ or the temperature of the air and converts the measurands into a standard signal of 0 - 10 V or 4...20 mA. It has four switchable temperature ranges and is applied in non- aggressive dust-free atmospheres in refrigeration, air conditioning, ventilation and clean room technology. Relative humidity (in % r. H.) is the quotient of water vapour partial pressure divided by the saturation vapour pressure at the respective gas temperature. These measuring transducers are designed for exact detection of humidity. A digital long-term stable sensor is used as measuring element for humidity measurement. Fine adjustment by the user is possible.
