AFTF-20-I Q DISPLAY

HYGRASGARD® AFTF-20-I Q_LCD

Item No. 2003-6122-2100-001

Calibratable outdoor humidity and temperature sensor HYGRASGARD® AFTF - 20 (± 1,8 %) with plastic sinter filter (optional metal sinter filter), housing made from impact-resistant plastic, optionally with/ without display, with cable gland or bushing for M12 connector according to DIN EN 61076-2-101.

Calibratable outdoor humidity and temperature sensor HYGRASGARD® AFTF - 20-VA (± 1.8 %) with metal sinter filter, rugged housing, stainless steel V4A, optionally with/ without display, with cable fitting or bushing for M12 connector according to DIN EN 61076-2-101.

It measures the relative humidity and the temperature of the air and converts the measurand into a standard signal of 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 and 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.
