4. Operating Principle
The humidity annex switch, Model AFS-G3, serves to monitor condensed water
formation. The hygroscopic module of the measuring instrument is arranged on
an aluminum base plate so that the measuring element is near the mounting
plate. Protected by the housing, relative humidity close to the dew point allows
condensation to form inside. The aluminium base plate is close to the cooling
tube and transmits cooling energy to the measuring element. The measuring
point can be set inside. The threshold should be adapted for local conditions. The
microswitch trips a potential-free SPDT with silver contact plates rated max 2A /
48 V and 100 mA / 20 VAC/DC. The AFS requires no supply voltage.
