Publish Time: 2025-03-17
As a key component in the field of modern industrial automation and precision measurement, the rebound displacement sensor has played an irreplaceable role in many application scenarios with its unique working principle and technical characteristics. This type of sensor uses compressed air for inflation and automatically rebounds after deflation, thereby achieving high-precision and high-stability displacement measurement functions. Next, we will explore the technical characteristics, working principles and wide application fields of the rebound displacement sensor in depth.1. Technical characteristics and working principlesThe core advantages of the rebound displacement sensor lie in its high performance, high precision and high stability. Through the precise control of compressed air, this type of sensor can achieve a measurement range of 0-4mm and has a repeatability of up to 1μm. This high-precision measurement capability makes the rebound displacement sensor particularly important in industrial applications that require fine control.Specifically, the working principle of the rebound displacement sensor is based on the differential transformer principle. When the iron core in the sensor moves with the displacement of the object being measured, it changes the magnetic induction intensity between the primary coil and the secondary coil, thereby generating a voltage signal output that is linearly related to the displacement. After processing, this voltage signal can accurately reflect the actual displacement of the measured object. It is worth noting that the rebound displacement sensor adopts the compressed air inflation drive method, which not only improves the measurement stability, but also enables the sensor to automatically rebound to the initial position after deflation, greatly enhancing its reliability and service life.2. Structure and outlet methodThe structural design of the rebound displacement sensor is compact and reasonable, mainly composed of iron core, coil skeleton, shell and other components. In order to adapt to different usage scenarios and needs, this type of sensor also provides a variety of outlet methods, including straight outlet and side outlet. The straight outlet method is suitable for occasions with relatively spacious space, and can directly lead out the measurement signal line; while the side outlet method is more suitable for environments with limited space, and can smoothly lead out the signal line without interfering with other equipment.3. Application fieldThe rebound displacement sensor has been widely used in many fields due to its high precision and high stability. The following are some specific application scenarios:Semiconductor manufacturing: In the semiconductor manufacturing process, the flatness of the wafer has a vital impact on the performance of the chip. The rebound displacement sensor can accurately measure the tiny displacement changes on the surface of the wafer, thereby ensuring the stable quality of the wafer.Optical film preparation: The thickness and uniformity of the optical film have a direct impact on its optical properties. The rebound displacement sensor can be used to monitor the thickness changes during the film deposition process to ensure the quality and performance of the film.Precision machining: In the field of precision machining, the rebound displacement sensor can be used to measure the displacement of the tool or workpiece to ensure the processing accuracy and product quality. For example, the use of rebound displacement sensors on CNC (computer numerical control) machine tools can improve the accuracy and efficiency of processing.Automated production line: On the automated production line, the rebound displacement sensor can be used to detect the position information of the workpiece to guide the robot or other automated equipment to perform precise operations. This helps to improve production efficiency and reduce human errors.Material science research: In material science research, the rebound displacement sensor can be used to measure the tiny deformation of the material under stress, thereby helping researchers understand the mechanical properties and deformation mechanism of the material. This is of great significance for the development and application of new materials.Rebound displacement sensors play an important role in the field of modern industrial automation and precision measurement with their unique working principle and technical characteristics. Whether it is semiconductor manufacturing, optical thin film preparation or precision machining, they are inseparable from the support of high-precision and high-stability rebound displacement sensors. With the continuous advancement of science and technology and the continuous improvement of industrial automation level, it is believed that rebound displacement sensors will be widely used and developed in more fields.
