Oil Detector & Alarm for Cooling Water ORGS
Use oil detector & alarm ORGS 11-2 only for signalling ingress of oil in cooling water systems.
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 electronic module integrated in the terminal box. The electrode operation is based on the conductive measuring principle using 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 downstream 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.
Oil is not electrically conductive, which means that no current can flow between the electrode rods of the measuring electrode. In this case the oil detector & alarm will signal
ingress of oil and trigger an alarm.
The amount of oil necessary to signal ingress of oil depends on the design of the measuring pot and the length of the electrode rods. The measuring pot is matched to the ectrode
such that ingress of oil is signalled when the oil content limit of approx. 50 ml is reached.
The equipment can detect all substances that are insoluble in water, not emulsified and lighter than water. In addition, the equipment can also detect all liquids with aconductivity value below the adjusted response sensitivity.
