SENSORS FOR AGRICULTURAL MACHINERY Powerful sensors to meet growing demands

In industrial livestock farming, pallet forks are used as attachments for tractors for transporting feed. Drawwire sensors are used to measure and control the raising and lowering of the pallet forks. When it comes to storing and stacking hay bales in particular, the ability to control the attachments precisely speeds up the work process, saving time and money.

Draw wire sensors are inexpensive and compact sensors that precisely measure the position or change in position of objects. The core components of a draw-wire potentiometer are a precision measuring wire and a sensor element that converts the change in position into a proportional electrical signal. The maintenance-free draw wire encoders are particularly quick and easy to install and are used in all areas of industry due to their reliability. 1 based on the measurement range WayCon ► Sensors for agricultural machinery 03

Combine harvester Combine harvesters are harvesting machines that are used to cut and thresh grain. Modern combine harvesters make it possible to harvest grain on a huge scale. Angle sensors, such as the WPH series with its wear-free Hall-effect sensor element, are installed in the cutting unit to monitor whether the cutting angle and alignment are correct. This is crucial in ensuring that the cutter bar always remains in the optimum position to guarantee consistent harvesting performance. Angle sensors are also used in the steering systems of self-propelled mowers. WayCon ► Sensors for agricultural...

Rotary sensors, also known as encoders, detect angular changes in rotating parts with maximum precision. The WPH series is equipped with a Hall-effect sensor element that allows wear-free measurement. In addition, the WPH series can be provided with increased corrosion protection to protect the sensor from aggressive media. The M36/M58 series also has a wear-free measuring principle with its magnetic sensor element. 1 based on the measurement range WayCon ► Sensors for agricultural machinery 05

Disc harrow Disc harrows are used in farming to plough up and aerate the soil. This encourages volunteer grains to germinate more quickly. Linear potentiometers are mounted on disc harrows to ensure efficient soil cultivation. The durable linear sensors measure the alignment of the harrow and use this to determine the cultivation depth. Optimum alignment can increase the operating speed and reduce the amount of working time. WayCon ► Sensors for agricultural machinery

Linear potentiometers are a cost-effective and reliable way of measuring distances or positions. The linear potentiometers work as voltage dividers via a hybrid plastic layer and are available with a protection class of up to IP67. Linear potentiometers combine simple design with maximum precision. A wide variety of designs and mounting options allow them to be used in countless applications. 1 based on the measurement range WayCon ► Sensors for agricultural machinery 07

Field sprayers Field sprayers are agricultural machines that are used to apply pesticides and fertilisers. The height control mechanism of the spray booms relies on ultrasonic sensors and is important to ensuring the product is applied as evenly as possible. Maintaining the optimum distance from crops and soil reduces costs and protects the environment. Ultrasonic sensors can also be used to automate field sprayers.

Ultrasonic sensors measure the distance to the target without contact, regardless of colour and material. The ultrasound is a high-frequency oscillation emitted by the sensor, which is reflected by the measurement object and received again in the form of an echo. The sensor calculates an analog output signal proportional to the distance from the transit time of the sound. A classic application for ultrasonic sensors is level measurement. 1 based on the measurement range WayCon ► Sensors for agricultural machinery 09

Grape harvester Grape harvesters are self-propelled machines that are used to harvest grapes. Careful handling of the delicate grapes is of the utmost importance, but the vines must not be exposed to too much stress either. Magnetostrictive sensors are used to adjust the shaking rods and the guidance system. The precise sensors ensure that grapes and vines are not damaged during the harvest.

The stroke measurement of cylinder pistons places special demands on the sensor technology. Magnetostrictive encoders from the MSB series and linear potentiometers from the LME and LMI series are installed directly in cylinder pistons. The MSB series enables contactless and wear-free distance measurement and can withstand working pressures of up to 350 bar. The LME and LMI series are suitable for pneumatic applications up to 20 bar (LME) and hydraulic applications up to 250 bar (LMI). 11 based on the measurement range WayCon ► Sensors for agricultural machinery 11
