Typical applications ■
In steam boiler and hot-water plants, the oil and turbidity detector can monitor any ingress of oil or grease
into the condensate, the feedwater or the water circuit (EN 12952-7, EN 12953-6). 2 detectors are required for
72 hrs operation.
■
In addition, the oil & turbidity detector is suitable for monitoring untreated and treated water (gravel filters,
full demineralisation systems, reverse osmosis systems) as well as waste water.
■
In the food sector, the oil and turbidity detector is used in the brewing and beverage industry (filtration, monitoring
of flavouring, quality assurance, etc.) and for monitoring filtration in the production of cooking oil.

Technical Data
Use oil and turbidity detector OR 52 for monitoring transparent liquids to detect any ingress of light-scattering and insoluble
foreign matter.
The OR 52-5/-6 oil and turbidity detector consists of a type
ORG 12 or ORG 22 measuring sensor and type ORT 6 measuring transducer that acts as an operating and display unit.
The correct measuring sensor is selected depending on the fluid used.
The oil & turbidity detector is used to detect impurities in transparent liquids. It is chiefly employed in industry and
the food sector, in which high levels of reliability and ease of maintenance are essential.

Function
Measuring transducer ORT 6
The measuring sensor is a photometric measuring device.
It consists of a light source (light emitter) and two photoelectric cells that make up a light receiver. A constantly
maintained beam of light shines through the transparent liquid. Undissolved foreign particles scatter the beam, which
is measured using the 15° forward-scattered light principle. This scattered light is then converted into an electrical
current and analysed to determine the content of foreign matter.
The measuring transducer is the operating and display unit for actuating the measuring sensor and
analysing the signals. It visually displays the measurement results and is used to set the measuring equipment. It displays the actual value, the triggering of
ALARM 1 and ALARM 2 limit value alarms and malfunctions in the measuring sensor. Limit values are set and displayed
on the measuring transducer.
Use in potentially explosive atmospheres Do not use the equipment in potentially explosive atmospheres.
