Room sensor
KWL-FTF eC
Installation and operating instructions
a measuring element for humidity and temperature measurement. Fine adjustment
by the user is possible.
Any use other than the intended use is prohibited!
1.8 Functionality
The calibratable room humidity and temperature sensor KWL-FTF eC measures
the relative humidity and ⁄ or temperature of air. It converts the measured variables
of humidity and temperature into a bus signal. In an elegant housing made of plastic,
with snap-on lid, base with 4-hole attachment for installation on vertically or hori-
zontally installed in-wall flush boxes, with predetermined breaking point for on-wall
cable entry. The relative humidity (in % r.H.) is the quotient of water vapour partial
pressure divided by the saturation vapour pressure at the respective gas tempera-
ture.
