ENGLISH
Use oil and turbidity detector OR 42/OR 52
only for monitoring of transparent liquids to
detect any ingress of insoluble and
refracting foreign matter, for measuring of
turbidity and signal evaluation for indication
and recording as well as for tripping of
alarms, control valves etc.
The equipment must only be installed by
qualified staff.
Before installing the oil and turbidity detector
cut off power supply.
All repairs must be performed only by the
manufacturer. Misuse or any attempted
modification of the equipment will endanger
plant safety.
Important Safety Note
The terminal strip of the ORT4/ORT5 is live
during operation. This presents the danger
of electric shock. Cut off power supply
before opening the equipment or
undertaking any maintenance work
Warning
The oil and turbidity detector OR 42/OR 52
consists of the sensor ORG 12/ORG 22
and the measuring transducer ORT 4/
ORT 5.
Application:
■ In steam boiler plants: Monitoring of
condensate returned to the boiler for oil
and grease contamination, in particular
for boilers operating without constant
supervision acc. to TRD 604 (2 detectors
are required for 72 h operation)
■ For raw-water monitoring and water
treatment (sand filters, demineralization
plants, reverse-osmosis plants)
■ For waste-water monitoring
■ In breweries and the beverage industry
(filtration, monitoring of wort, quality
assurance etc.)
■ For salad oil production: Monitoring of
filtering process
■ For marine applications: Monitoring of
filtering equipment in accordance with
IMO (International Maritime Organization)
resolution MEPC.60(33) – when certain
cold cleaning agents that split up easily
are used which cannot form stable water/
oil emulsions
Purpose
The oil and turbidity detector measures the
intensity of the scattered light produced by
foreign matter that is not dissolved in trans-
parent liquids and exposed to incident light,
with emulsified oils scattering incident light
mainly in the forward direction.
In the oil and turbidity detector the forward
scattered-light principle is applied which
provides a high sensitivity for emulsified
greases and oils and other organic matter.
