German WABCO sensors, WABCO models, WABCO prices

WABCO sensors are devices that convert mass signals into measurable electrical signal outputs. When using sensors, the actual working environment of the sensor should be considered first. This is crucial for the correct selection of load cells, as it affects whether the sensor can work normally, its safety and service life, and even the reliability and safety of the entire weighing system. There are qualitative differences between the old and new national standards in the basic concepts and evaluation methods of the main technical indicators of load cells. The main types include S type, cantilever type, spoke type, plate ring type, membrane box type, bridge type, and column cylinder type.

WABCO sensor classification

1) Linear displacement sensor: The function of a linear displacement sensor is to convert linear mechanical displacement into an electrical signal. To achieve this effect, a variable resistor slide rail is usually fixed at a fixed position of the sensor, and different resistance values are measured by the displacement of the slider on the slide rail. The sensor slide rail is connected to a stable DC voltage, allowing a small current in microamperes to flow. The voltage between the slider and the starting end is proportional to the length of the slider's movement. Using the sensor as a voltage divider can minimize the requirement for the accuracy of the total resistance of the slide rail, because resistance changes caused by temperature changes will not affect the measurement results. 2) Angular displacement sensor: Angular displacement sensors are used for obstacle handling: using angle sensors to control your wheels can indirectly detect obstacles. The principle is very simple: if the motor angle sensor structure is operating but the gear does not turn, it means your machine is blocked by an obstacle. This technology is very simple to use and very effective; the only requirement is that the moving wheels must not slip on the floor (or slip too many times), otherwise you will not be able to detect obstacles. Connecting an idling gear to the motor can avoid this problem. This wheel is not driven by the motor but is driven by the movement of the device: during the rotation of the drive wheel, if the idler wheel stops, it means you have hit an obstacle.

Precautions for using WABCO sensors

1) If the electronic scale has been in use for a long time, and the seal has aged while accumulating many impurities, water mixtures and oil will seriously affect the contact resistance of the brushes, causing the displayed numbers to jump continuously. In this case, the electronic scale of the linear displacement sensor can be considered damaged and needs to be replaced. 2) If the power supply capacity is too small, various issues may arise; therefore, the power supply must have sufficient capacity. Insufficient capacity can cause the following situations: the movement of the plasticizing unit causes fluctuations in the display of the mold-clamping electronic scale, or the movement of the mold-clamping unit causes fluctuations in the display of the injection electronic scale, resulting in significant measurement errors. These situations are more likely to occur when the drive power for the solenoid valve and the power supply for the linear displacement sensor share the same source. In severe cases, voltage fluctuations can even be measured using the voltage range of a multimeter. If the issue is not caused by high-frequency interference, electrostatic interference, or poor neutral grounding, it is likely due to insufficient power supply capacity. 3) Frequency modulation interference and electrostatic interference can both cause the displayed numbers on the electronic scale of the linear displacement sensor to jump. The signal cables of the electronic scale must be routed in separate cable ducts from the high-voltage lines of the equipment. The electronic scale must be forcibly mounted using a grounding bracket, ensuring good contact between the housing of the electronic scale and the ground. Shielded cables must be used for signal lines, and one end of the shield should be grounded at the electrical cabinet. When high-frequency interference is present, voltage measurements with a multimeter usually appear normal, but the displayed numbers continue to jump. Electrostatic interference produces similar symptoms. To verify whether electrostatic interference is the cause, briefly short-circuit the cover screw of the electronic scale to a metal part of the machine using a power cord. Once short-circuited, the electrostatic interference will be eliminated immediately. However, this method is difficult to apply for eliminating high-frequency interference. Since frequency converters and robotic arms often generate high-frequency interference, you can try stopping the high-frequency energy saver or the robotic arm to verify if high-frequency interference is the cause. 4) If the display data of the electronic scale of the linear displacement sensor jumps regularly at a certain point during operation, or if there is no display data, check whether the insulation of the connection wires is damaged and causing regular contact with the machine housing, leading to a ground short circuit. 5) The supply voltage must be stable. Industrial voltage stability must comply with ±0.1[%]. For example, if the reference voltage is 10V, a fluctuation of ±0.01V is permitted. Otherwise, significant display fluctuations may occur. However, if the amplitude of the display fluctuation does not exceed the amplitude of the voltage fluctuation, the electronic scale is functioning normally. 6) The alignment of the linear displacement sensor must be precise. However, a parallelism error of ±0.5mm and an angular error of ±12° are permissible. If both the parallelism and angular errors are excessive, the displayed numbers will jump. In such cases, the parallelism and angle must be adjusted. 7) Pay close attention during connection. The three wires of the electronic scale must not be connected incorrectly, and the power and output lines must not be swapped. Incorrect wiring will result in significant linearity errors, making control difficult and reducing control precision. It may also cause frequent jumping in the display.

WABCO sensor applications

The geometric state parameters of train wheel flanges affect the speed and smoothness of train operation and are very important for the safe operation of trains. Traditional detection methods are relatively complex, usually using special rulers with verniers for measurement. Manual reading of data causes large measurement errors and cannot achieve digital management of detection data. With the development of China's railway industry, train speeds are increasing, making precise and rapid inspection and digital management of train wheel flange state parameters increasingly important. The flange detector adopts modern sensor technology, a microcontroller processing system, and a concise and stable mechanical structure, enabling convenient and precise continuous rapid measurement of geometric state parameters, achieving digitization of parameters such as flange height and rim thickness. Many sensors are used for detecting flange height, width, rim thickness, etc., with displacement sensors being the most concerned. There are many types of displacement sensors. Currently, a new type of sensor technology called laser displacement sensors is used for train wheel flange shape detection. The laser triangulation method currently used for train wheel flange detection has high precision for short-distance measurements. The displacement sensor can be directly installed on the track for detection, or a laser reflective displacement sensor can be used as the measuring device. The laser sensor module scans the flange shape along a straight line direction while recording the entire flange data. The entire flange contour curve can be obtained through a microprocessor, thereby calculating flange width, flange height, 70mm wear amount, and wear area, etc. The measured data can be uploaded to a computer to generate a database, utilizing advanced post-processing software for digital management of train wheel flanges. It can not only measure the wear of wheel pairs on online operating trains but also sort out whether wheel pair dimensions are qualified on the production line. The development of transportation is inseparable from detection technology, and instruments, meters, and sensor technology are the core of detection technology. In today's era of rapid power development, people not only hope to experience comfort and enjoyment but also desire safety. The development of sensor technology will bring more safety to people's lives and transportation, and the development of sensor technology in China will also drive the development of world-class advanced technologies in transportation internationally.
