AGRICULTURAL EQUIPMENT APPLICATIONS The agricultural equipment industry is increasing utilising automation and thus its demands for low-cost, performance and robustness, make Contrinex sensors ideal and popular in this sector.
To monitor the speed of industrial composting machines, robust and reliable V4A/ 316L stainless-steel 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. An equipment 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. Even under the harsh operating conditions of this application, FULL INOX sensors last several years and downtime attributable to faulty sensors is minimal. Their long service life contributes to a reduction in repair costs.
APPLICATION - COMPOST TURNING EQUIPMENT
APPLICATION - POSITION SENSING OF REAR-WHEEL STEERING
A range of multi-purpose off-road tractors allows the driver to choose between two-wheel or four-wheel steering. When selecting two-wheel steering using the front wheels only, the rear axle is locked in the straight-ahead position. Before the axle is locked, rugged inductive sensors from Contrinex detect the straight-ahead position accurately and reliably, ensuring precise alignment of the tractor’s steering geometry. CUSTOMER APPLICATION Modern multi-purpose off-road utility vehicles are exceptionally versatile, offering four-wheel drive and both front and rear-wheel steering. Reliable operation all year round, on all types of terrain and in all weather conditions, is essential as typical tasks include bulk-load transportation and agricultural engineering. Extreme conditions often demand increased manoeuvrability; for maximum control, the driver can engage four-wheel steering when required. When reverting to the default two-wheel steering configuration, the rear axle must be locked in the straight-ahead position to prevent misalignment of the rear wheels. A rugged, reliable and accurate sensor system is required to detect the straight-ahead position of the rear axle before it is locked. The sensor must withstand significant mechanical shock and vibration and must also be impervious to water ingress. Additionally, it should accommodate the extremes of temperature experienced during all- year-round operation.
Customer Solution Inductive sensors from the Contrinex ‘Basic’ range are rugged, reliable and accommodate the required extremes of temperature; with an M8- sized sensor being ideal for this application. A V2A/AISI 303 stainless-steel body and vacuum-encapsulated electronics, make it particularly suitable for the mechanically demanding environment, and it is rated for operation at temperatures between -25ºC (-13ºF) and 70ºC (158ºF). A narrow flange is attached to each end of the vehicle’s hydraulic power-steering rack. The sensor is mounted immediately below one end of the rack and detects the position of the flange as it passes over the sensing face. The sensing distance of 2mm eliminates any possibility of accidental collision with the flange. Configured with an industry-standard PNP normally-open interface, the sensor features an integral M8 connector and connects to the vehicle’s central controller via a flexible PVC-sheathed cable. Adding the sensor requires minimal modification to the vehicle’s control systems, and maintenance is simple and speedy. The sensor detects the straight-ahead position of the vehicle’s rear axle repeatably and accurately, ensuring correct, reliable engagement of two-wheel steering. Contrinex inductive sensors provide the customer with a cost-effective fit-and-forget solution to a challenging problem.
