HELPING YOU #MAKE SENSE OF SENSORS
EXAMPLE APPLICATIONS
TO ILLUSTRATE THE WIDE-VARIETY OF APPLICATIONS SOLVED USING
CONTRINEX SENSORS, WE HAVE POSTED A LARGE SELECTION OF
EXAMPLE APPLICATIONS WHICH CAN BE SEEN BY CLICKING ON AN IMAGE.
BELOW ARE A SELECTION OF SOME OF THESE APPLICATIONS:
APPLICATION - WASHDOWN SENSORS
MONITOR CLEAN-IN-PLACE CIP AT A DIARY
Food-grade washdown inductive sensors from Contrinex are
completely compatible with the strict hygiene standards of
the dairy industry, helping maximize plant utilisation during
round-the-clock production of milk-based foodstuffs. Rated to
IP68/IP69K, Contrinex stainless-steel washdown sensors
withstand both aggressive cleaning chemicals and high-
pressure water jets, offering highly robust solutions for the
harshest operating environments.
Food-grade sensors are available with IO-Link, a standardized
serial connection protocol, providing digital communication in
washdown areas at no additional cost.
CUSTOMER APPLICATION
Cleanliness is everything in food-processing facilities, and
nowhere more so than in the dairy industry. A single instance
of contamination during production can necessitate the
destruction of multiple batches of milk-based foodstuffs - or, if
undetected, result in illness, disease or death among
consumers of infected products. It’s no surprise that for dairy-
plant operators, maintaining the strictest possible hygiene
standards is an absolute must.
Given the simultaneous need to maximize plant utilization,
time-consuming cleaning methods are highly undesirable. To
avoid lengthy unproductive intervals between batches, food-
processing facilities commonly utilise clean-in-place (CIP) and
high-pressure washdown systems. Production equipment for
washdown areas must therefore withstand both aggressive
cleaning chemicals and high-pressure water jets as a matter of
course. This requirement extends to the sensors used
throughout these areas.
CUSTOMER SOLUTION
The Contrinex Washdown range of food-grade inductive
sensors addresses these needs perfectly. Devices from both
the Series 600 Classics and Series 700 Full Inox families are
certified to operate continuously and reliably in harsh
conditions. Rated to IP68/IP69K, they are pressure-resistant up
to 80 bar, corrosion-resistant and ideal for use in food and
beverage industries. Sensing the presence and detecting the
position of equipment or materials at each stage requires
sensors that are both accurate and responsive.
Contrinex Washdown inductive sensors are up to the task in all
respects. With a choice of one-piece M12-, M18- or M30-
diameter AISI 316L /V4A stainless steel bodies and sensing
faces (Full Inox family) or M12-diameter AISI 316L/V4A stainless-
steel body and PPS (polyphenylene sulphide) FDA-approved
sensing face (Classics family), these fully embeddable
inductive sensors offer a highly robust solution for the harshest
operating environment. Industry-standard PNP or NPN
outputs with an integral M12 connector and IP69K-rated cable
set ensure compatibility with existing factory systems.

INDUSTRY 4
Agriculture is using increasingly complex automation in its
machinery and an example application is in composting
machines. Contrinex’s uniquely robust V4A/ 316L stainless-steel
sensors are relied upon for operating reliably in the
challenging environment of the inside of the machine’s drive
rotor. Withstanding dust, humidity and high temperatures, the
sensors enable the machine to provide the fast drying of
materials and optimal decomposition with reliable sanitisation
being ensured.
CUSTOMER APPLICATION
The efficient turning of organic materials – loosening, lifting
and aerating – is vitally important in industrial composting.
Special mobile equipment ensures fast drying of materials,
optimal decomposition and reliable sanitisation, processing
between 500 and 6800 cubic meters of earth per hour.
A manufacturer has introduced machine speed monitoring by
sensor. A sensor located in the rotor counts the passing teeth
of a rotating mechanical disk. From the number of teeth per
second, the controller then calculates the final speed.
Perfect sensor operation is required under these particularly
harsh conditions. In addition to permanent vibration and
shaking, the inductive sensor is also constantly exposed to
dust, moisture, and temperatures from 70 to 80°C (158 to
176°F). Since the location of the sensor in the rotor is hard to
access, the sensor must be very durable and low maintenance
to avoid time-consuming repairs.

RELIABILITY
During manufacture of dairy products, raw milk travels
between successive processes through stainless-steel
pipework. Rotary-shaft control valves maintain process
sequences correctly, ensuring that no cross-contamination
occurs during CIP cleaning after each batch is completed.
Robust washdown inductive sensors, mounted on existing
rotary actuators, monitor control-valve status around the clock,
providing real-time positional feedback to a plant-wide control
system in a simple, cost-effective manner.
CUSTOMER APPLICATION
At a European dairy-processing plant, milk products, made
from pasteurized or raw milk, require hygienic transportation
between successive operations. Process engineers use
stainless-steel pipework to transport liquid ingredients from
one operation to the next. Fluid flow is managed using control
valves fitted with electrical, hydraulic or pneumatic actuators.
Multiple rotary-shaft valves deliver raw milk from holding
tanks to each process station in sequence, maintaining
specified flow rates and volumetric limits. Once processing of
each batch is completed and all process vessels are drained,
closed-loop CIP cleaning commences. Accurate, repeatable
valve sequencing is essential to prevent any chance of cross-
contamination between processing and cleaning sequences.
A robust, highly reliable sensor system, capable of
withstanding the harsh washdown regimes in force, is needed
to monitor control-valve positions during processing. Where
possible, sensors must be mounted on existing rotary
actuators, and real-time communication with existing plant-
wide control systems is mandatory.
APPLICATION - WASHDOWN INDUCTIVES
MONITOR DAIRY VALVE STATUS
Customer Solution
Sensing the position of a rotary-valve actuator is a routine task
for Contrinex Classics washdown inductive sensors. These
sensors interface directly with a range of industrial process
controllers and provide cost-effective confirmation of control-
valve status around the clock.
A purpose-designed bracket, mounted on the top surface of
each actuator, holds two sensors; these are positioned with the
sensing faces vertically aligned, one above the other, and
facing the actuator shaft. NAMUR-compatible (VDE/VDI 3845)
mountings on the actuators provide a known datum for the
sensors.
A solid plastic disc, mounted on the shaft, carries two or more
stainless-steel targets, positioned at 90 degrees to each other
around the outer peripheral surface of the disc. Each target
occupies either an upper or a lower position corresponding to
height of one of the sensors. As the shaft rotates, opening and
closing the valve, the targets pass in front of the sensing faces,
triggering the sensors.
These M12-diameter devices, rated to IP68/IP69K, have all-
metal bodies with PBTB sensing faces and vacuum-
encapsulated electronics; each features an industry-standard
PNP normally open output. Fully embeddable, and with a
sensing range up to 2mm, they are well suited to the hostile
operating conditions of a washdown environment.
Each sensor has an integral M12 connector, interfacing with
the customer’s control system via a TPE-S-sheathed cable.
Reliability is excellent; the system is simple and cost-effective.
THE INNOVATIVE 700-SERIES INDUCTIVE SENSOR FAMILY ALSO INCLUDES ENHANCED CORROSION
RESISTANCE WITH THE ‘WASHDOWN’ 316L/ V4A STAINLESS-STEEL VERSIONS.

WASHDOWN 316L/V4A STAINLESS-
STEEL 700 SERIES INDUCTIVE SENSORS
CUSTOMER SOLUTION
Contrinex inductive sensors from the FULL stainless-steel
family, WASHDOWN range, are perfect for this application.
Made from a single piece of V4A stainless steel, including the
sensing face, they have no covers, caps or welding seams and
are the most robust inductive sensors on the market. They
resist shock, vibration, impact and abrasion and almost any
exposure to dirt, gases, or liquids such as oil, water and
cleaning agents. Functionally stable at temperatures from -25
to +85°C (-13 to 185°F), they are also insensitive to core
breakage.
Thanks to the long operating distances of these sensors (three
times greater than the norm) a compact and efficient design
was possible using the M12 size. A long operating distance
allows the sensor to be mounted well away from the rotating
disk’s passing teeth. Setup is also straightforward, as
installation tolerances are less critical. A sensor version with
plug connector was chosen to allow speedy replacement if
necessary.
