Page 4: Operating Principle
AFK-A/AFK-F/AFK-T/AFK-S 5. Operating Principle The sensors of the AFK-A and AFK-F series measure humidity by means of a humidity-dependant condenser. The capacitive humidity measuring element, produced using thinfilm technology, consists of a base plate, on which the electrodes are housed and a hygroscopic polymer layer above it. The hygroscopic polymer layer absorbs water molecules from the medium to be measured (air) or releases them, thereby altering the capacity of the condenser. -
Page 5: Mechanical Connection
In order to maintain interference immunity in accordance with EN 61326 when it is in use, we recommend to use a screened cable (e.g. type 8x AWG26 C UL) for connecting the sensors, and have this fitted into the sensor’s EMC heavy-gauge conduit thread by a qualified electrician.

Page 6: Electrical Connection
Pay attention to the load according to the operating voltage when using sensors with a current output. Lines to and from the sensor must not be installed parallel to strong electromagnetically fields. If there is any chance of an electrical surge, please install surge protection devices.
