Design of speed sensor based on high temperature resistant environment
With the development of industries,speed sensors have become an important support for the development of modern industrial automation.It plays a significant role in automobile,mechanical manufacturing,and aerospace industries.High temperature speed sensors are commonly used for monitoring and measuring the motion status of rotating machinery in high-temperature environments.The sensors provide real-time data to the acquisition system,helping to monitor and prevent equipment failures,extend equipment life,and ensure equipment safety performance.Basic principles,structural design,and material selection of high-temperature magneto electric speed sensors are introduced,and test data are given and the test results are analyzed.The result shows that rotational speed measuring can be realized in an environment of 350℃.
