Germany EUROSTAMPI sensor EUROSTAMPI model EUROSTAMPI price

EUROSTAMPI sensors are devices that convert mass signals into measurable electrical signal outputs. When using a sensor, the actual working environment of the sensor must be considered first; this is crucial for the correct selection of load cells, as it affects whether the sensor can operate normally, its safety and service life, and even the reliability and safety of the entire weighing instrument. There are qualitative differences between the old and new national standards regarding 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.

EUROSTAMPI 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 stationary part of the sensor, and different resistance values are measured by the displacement of the wiper 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 wiper and the starting end 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 slide rail, 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 an angle sensor 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 has been 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 be unable 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 indicates that you have encountered an obstacle.

Precautions for using EUROSTAMPI sensors

1) If the electronic scale has been used for a long time, and the seal has aged while containing 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, it can be said that the electronic scale of the linear displacement sensor is 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 drive 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 neutrality, 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 lines of the electronic scale and the high-voltage lines of the equipment must be separated in different wire trays. The electronic scale must mandatorily use a grounding bracket, and ensure 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 shielded cable should be grounded at the electrical box. When there is high-frequency interference, measurements using the voltage range of a multimeter usually appear normal, but the displayed numbers will 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 data displayed at a certain point jumps regularly during the operation of the linear displacement sensor's electronic scale, or if there is no display data, check whether the insulation of the connection line 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 significant 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 too large, the displayed numbers will jump. In such cases, parallelism and angularity must be adjusted. 7) During the connection process, 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 large linear errors, making control difficult and reducing control precision, while the display is prone to jumping.

EUROSTAMPI 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 specialized rulers with verniers for measurement. Manual reading of data leads to larger measurement errors and prevents digital management of detection data. With the development of China's railway industry, train speeds are increasing, making precise and rapid inspection of train wheel flange state parameters and digital management 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 primary focus. There are many types of displacement sensors; the current novel sensor technology 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 direction 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 amount, and wear area. 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 wheel set wear on trains in operation but also sort wheel sets 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 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 development of world-class advanced technologies in the transportation sector internationally.
