to detect the building of condensed water
with Polyga® measuring element
Changeover contact with silver contacts
Breaking capacity max. 48VAC
The hygrostat module on PCB with Polyga® measuring element is arranged on an aluminium base plate so that the measuring element is in an immediate proximity to the base plate.
Protected by the housing, relative humidity near to dew point can form inside. The aluminium plate is adjacent to the cooling pipe and transfers the cold to the measuring element. The set point can be set inside and has to be adapted to the local conditions.
The microswitch of the hygro module switches a changeover contact potential-free. The standard switch is lined with silver contacts. Optionally there is a microswitch with gold contacts. The FAS does not require a supply voltage resp. auxiliary energy.
