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.

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.
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.

To monitor the speed of industrial composting machines, robust and reliable FULL INOX sensors operate continuously inside the rotor, withstanding dust, humidity and high temperatures. Fast drying of materials, optimal decomposition and reliable sanitization are assured. 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 sanitization, processing between 500 and 6800 cubic meters of earth per hour. A German 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.
Customer Solution Contrinex inductive sensors from the FULL INOX 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.
