Description
Use oil detector & alarm ORGS 11?2 only for signalling ingress
of oil in cooling water systems.
Function
The oil detector & alarm ORGS 11?2 is an equipment unit
consisting of the measuring electrode ORGS 11-1 and a
measuring pot.
The measuring electrode ORGS 11-1 is a compact-type
system that comprises the measuring electrode and an elec?
tronic module integrated in the terminal box. The electrode
operation is based on the conductive measuring principle us?
ing the electrical conductivity of the water for signalling water
level. The electronic module detects whether the electrode
rods are submerged or exposed and, in the event of ingress
of oil, energises the output contacts.
A water sample, taken from the cooling water system down?
stream of the location at the highest point where ingress of
oil might occur, is fed from below into the measuring pot of
the ORGS 11-2. If the water is contaminated with oil, the oil
droplets - due to their lower density - ascend and accumulate
on top of the water and, consequently, the electrode rods are
now submerged in this oil film.
