The oil detector & alarm system works according to the conductivity measurement principle. The oil detector & alarm systemhas a switching controller integrated in its terminal box which controls all funtions. External switchgear is therefore not required.
A control and alarm system installed downstream of the equipment protects the installation be to cooled and prevents ingress of oil.
The equipment features two channels and the contact relays are of the normally closed type and will automatically signal alarm condition in the event of a malfunction.
