Publish Time: 2024-12-25
With the continuous development of industrial automation and precision measurement technology, pneumatic displacement sensor, as an innovative measurement tool, has gradually shown its unique advantages in various fields. This article will comprehensively introduce the working principle, characteristics, application fields and selection recommendations of pneumatic displacement sensor, and provide readers with a detailed reference guide.1. Working principle of pneumatic displacement sensorThe pneumatic displacement sensor adopts the working principle of compressed air inflation drive and automatic rebound after deflation. Its core is to drive the measuring head to move by blowing compressed air into the bellows chamber inside the sensor. When the displacement needs to be measured, the system controls the amount of compressed air charged to make the measuring head reach the predetermined position; after the measurement is completed, the compressed air is released, and the measuring head automatically rebounds to the initial position under the action of the elastic element. This frictionless and wear-free driving method ensures the high precision and long life of the sensor.2. Characteristics of pneumatic displacement sensorHigh performance: The pneumatic displacement sensor adopts advanced sensing technology and precise manufacturing process to ensure the high performance of the sensor. Its measurement range is wide, up to 2~10mm, meeting the needs of different application scenarios.High precision: The repeatability of the sensor is as high as 0.1um, which means that in multiple measurements, the sensor can provide very consistent and accurate results. This high-precision feature gives pneumatic displacement sensors a unique advantage in the field of precision measurement.High stability: Due to the use of compressed air drive, the sensor is not affected by environmental factors such as temperature and humidity during operation, ensuring the stability and reliability of the measurement.Ultra-light contact: For objects that require force measurement, such as glass, plastic, film, wafer, etc., pneumatic ultra-light contact displacement sensors can avoid secondary damage to the object. Its ultra-light contact force ensures the accuracy of the measurement and the integrity of the object.3. Application fields of pneumatic displacement sensorsPneumatic displacement sensors have been widely used in many fields due to their high precision, high stability and ultra-light contact.Industrial automation: In automated production lines, pneumatic displacement sensors can be used to monitor and control the motion state of mechanical parts to ensure the stability and efficiency of the production process.Precision measurement: In scientific research, laboratories and other fields, pneumatic displacement sensors can be used for high-precision displacement measurement to meet application scenarios with extremely high requirements for measurement accuracy.Medical equipment: In medical equipment, pneumatic displacement sensors can be used to monitor small displacement changes of human organs or tissues, providing doctors with accurate diagnosis basis.Semiconductor manufacturing: In the semiconductor manufacturing process, pneumatic displacement sensors can be used to measure the displacement changes of precision components such as wafers to ensure the accuracy and stability of the manufacturing process.4. Selection suggestions for pneumatic displacement sensorsWhen selecting a pneumatic displacement sensor, users should make comprehensive considerations based on actual needs. Here are some selection suggestions:Measurement range: Select a suitable sensor measurement range based on the displacement range of the object being measured. If the measurement range is too large or too small, it may lead to inaccurate measurement or sensor damage.Accuracy requirements: Select a suitable sensor accuracy level based on the accuracy requirements of the application scenario. If the accuracy requirements are too high, it may lead to increased costs; if the accuracy requirements are too low, it may not meet the actual needs.Outlet method: Select a suitable outlet method (straight outlet or side outlet) based on the installation environment and wiring requirements. Reasonable wiring method can simplify the installation process and reduce the failure rate.Contact force requirements: For objects that need to measure force, ultra-light contact displacement sensors should be selected to avoid secondary damage to the object.Pneumatic displacement sensors have shown broad application prospects in industrial automation, precision measurement, medical equipment and semiconductor manufacturing due to their high precision, high stability and ultra-light contact. When selecting a sensor, users should make comprehensive considerations based on actual needs and choose the sensor model that best suits them.
