Duct moisture sensor

HYGRASGARD® duct humidity sensors reliably and precisely measure the relative humidity and/or temperature in ventilation ducts, in refrigeration, air conditioning and clean room technology and convert the measured variables into a standard signal of 0-10 V or 4...20 mA. Some models also have a potential-free changeover contact as an output - ideal for flexible switching applications in building technology.
Many device groups can also display additional parameters: relative humidity [% r. H.], absolute humidity [g/ m³], mixing ratio [g/ kg], dew point temperature [°C], enthalpy [kJ/ kg] and ambient temperature [°C].
