HYGRASGARD® KAVTF-U DISPLAY

Item No. 1201-3161-6200-029
EAN 4 251325 610450

The universal humidity sensors HYGRASGARD® KAVTF with 6 output sizes are used to determine diverse measurands in humidity measurement. The relative humidity and temperature of the ambient air are measured. These measurands are used to calculate various parameters internally.

For device version x-U, two outputs of 0 - 10 V are available, for version x - I two outputs of 4...20 mA. Here, the output variables for these outputs can be defined using DIP switches. Selectable for output 1 are relative humidity [% r.H.], absolute humidity [g ⁄ m³], mixture ratio [g ⁄ kg], dew-point temperature [°C] or enthalpy [kJ ⁄ kg] (ignoring atmospheric air pressure). At output 2, four different measuring ranges for ambient temperature [°C] are selectable. The factory setting for output 1 is the relative humidity 0...100 % r.H., for output 2 the temperature measuring range 0...+50 °C. Due to the different configuration alternatives, numerous measurement and control tasks can be solved by just one device.

The devices are to be operated in pollutant-free, non-precipitating air with neither above-atmospheric nor below-atmospheric pressure at the sensors. Application examples include medical technology, refrigeration, air conditioning and clean room technology. The sensors are suitable for duct installation.
