OR52

The detector of oil and turbidity OR 52 is used for the detection of emulsions in transparent liquids. On condensate recovery networks in steam installations, a risk analysis is mandatory when the boiler is operated without permanent human presence. The turbidity detector is then used to monitor any pollution.

The OR52 consists of an ORG 12 (cast iron) or ORG 22 (stainless steel) sensor element and an ORT 6 measuring transducer as control and display device. It is mounted as a bypass of the main pipe, on either side of a non-return valve calibrated at 20 mbar. The ORG x2 detection element has a light source passing through a transparent cylinder, and two photoelectric cells assembled in a light receiver. The measurement uses the principle of scattering at 15° of a light ray encountering the droplets of the emulsion. Two upper connections allow the circulation of the liquid. The lower connection is used for draining or sampling. An internal scraper allows cleaning of the cylinder. The OTR6 measurement converter transforms the signal into an analog electrical current, indicating turbidity up to 25ppm Max. It is calibrated using a control filter at 20ppm. Equivalence curves exist between the displayed measurement and the values for different products. They make it possible to program 2 alarm thresholds, and their time delay, which can be used for signaling, or for actuating a safety valve. It can be installed on a support near the ORG x2.
