Any use other than the intended use is prohibited!
1.8 Functionality
The calibratable room humidity and temperature sensor AIR1/KWL-FTF 0-10V
measures the relative humidity and ⁄ or temperature of air. It converts the mea-
surands humidity and temperature into standard signals of 0 -10 V. In an elegant
housing made of plastic, with snap-on lid, base with 4-hole attachment for instal-
lation on vertically or horizontally installed in-wall flush boxes, with predetermined
breaking point for on-wall cable entry. The relative humidity (in % r.H.) is the quo-
tient of water vapour partial pressure divided by the saturation vapour pressure at
the respective gas temperature.
