German VERVENNE ET sensor VERVENNE ET model VERVENNE ET price

VERVENNE ET sensors, also known as linear sensors, are linear devices based on metal induction. The function of the sensor is to convert various measured physical quantities into electrical signals. In the production process, displacement measurement is generally divided into two types: measuring physical dimensions and mechanical displacement. According to the different forms of transformation of the measured variables, displacement sensors can be divided into analog and digital types. Analog types can be further divided into property-based and structural types. Commonly used displacement sensors are mostly analog structural types, including potentiometric displacement sensors, inductive displacement sensors, synchros, capacitive displacement sensors, eddy current displacement sensors, Hall effect displacement sensors, etc. An important advantage of digital displacement sensors is that they facilitate direct input of signals into computer systems. This type of sensor is developing rapidly and its applications are becoming increasingly widespread.

VERVENNE ET 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 track is usually fixed at a stationary part of the sensor, and different resistance values are measured by the displacement of the wiper on the track. The sensor track is connected to a stable DC voltage, allowing a small current in microamperes to flow. The voltage between the wiper and the start terminal is proportional to the length of the wiper's movement. Using the sensor as a voltage divider minimizes the requirement for the accuracy of the total resistance of the track, because resistance changes caused by temperature variations do not affect the measurement result. 2) Angular displacement sensor: Angular displacement sensors are applied in obstacle handling: using angle sensors to control your wheels can indirectly detect obstacles. The principle is very simple: if the motor angle sensor is constructed to operate but the gear does not turn, it indicates that your machine is blocked by an obstacle. This technology is very simple to use and highly effective; the only requirement is that the moving wheel must not slip on the floor (or slip too frequently), otherwise you will not be able to detect the obstacle. Connecting an idler 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.

VERVENNE ET sensor usage precautions

1) If the electronic scale has been used 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 brush, 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, many issues may arise; therefore, the power supply must have sufficient capacity. Insufficient capacity will cause the following situations: the movement of the molten glue will cause fluctuations or changes in the display of the mold clamping electronic scale, or the mold clamping movement will cause fluctuations in the display of the injection molding electronic scale, resulting in large measurement errors. If the driving power of the solenoid valve and the power supply of the linear displacement sensor are shared, the above situations are more likely to occur. In severe cases, voltage fluctuations can even be measured using the voltage range of a multimeter. If the situation 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 trays from the high-power lines of the equipment. The electronic scale must mandatorily use a grounding bracket, and ensure good contact between the housing of the electronic scale and the ground. Signal cables must use shielded cables, and one end of the shielded cable should be grounded at the electrical cabinet. When there is high-frequency interference, voltage measurements with a multimeter usually appear normal, but the displayed numbers keep jumping; the situation with electrostatic interference is similar to that of high-frequency interference. To verify whether it is electrostatic interference, you can short-circuit the cover screw of the electronic scale to some metal part of the machine using a power cord. Once short-circuited, the electrostatic interference will be eliminated immediately. However, it is difficult to eliminate high-frequency interference using the above method. Variable frequency drives and robotic arms often generate high-frequency interference, so you can try stopping the high-frequency drive or the robotic arm to verify if it is high-frequency interference. 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 cable is damaged and causing a regular ground short circuit due to contact with the machine housing. 5) The supply voltage must be stable. Industrial voltage requires stability within ±0.1[%]. For example, if the reference voltage is 10V, a fluctuation of ±0.01V is allowed. Otherwise, it will cause continuous fluctuations in the display. 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 installation must be good, but parallelism allows an error of ±0.5mm, and angularity allows an error of ±12°. However, if both parallelism and angularity errors are excessive, the displayed numbers will jump. In such cases, parallelism and angularity must be adjusted. 7) During connection, pay close attention: the three wires of the electronic scale must not be connected incorrectly, and the power line and output line must not be swapped. If the wires are connected incorrectly, it will result in significant linear error, making control difficult and reducing control precision, while the display is prone to jumping phenomena, etc.

VERVENNE ET sensor applications

The geometric state parameters of train wheel flanges affect the speed and smoothness of train operation and are crucial for safe train operation. Traditional detection methods are relatively complex, usually involving manual measurement with specialized calipers, which leads to significant measurement errors due to manual reading and prevents 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 wheel flange status 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, thus 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 of primary concern. There are many types of displacement sensors; the novel sensor technology currently used for train wheel flange detection is called laser displacement sensors. Currently, laser triangulation is used for train wheel flange detection, offering 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 while recording the entire flange data. The entire flange contour curve can be derived via a microprocessor, thereby calculating flange width, flange height, 70mm wear volume, and wear area, etc. Furthermore, 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 wheelset wear on trains in operation but also sort wheelsets on the production line based on dimensional compliance. The development of transportation relies on detection technology, with instruments and sensor technology being the core of detection technology. In today's era of rapid high-speed power development, people not only hope to experience comfort and enjoyment but also desire safety. The development of sensor technology will bring greater safety to people's lives and transportation, and the development of sensor technology in China will also drive the advancement of world-class technologies in the transportation sector internationally.
