The magnetostrictive displacement sensor developed and produced by our company has been extremely widely applied in the field of oil cylinder stroke detection due to its excellent performance. One of its outstanding advantages is the diversified installation methods, which can flexibly adapt to various complex working conditions. In this case, the sensor is applied to the detection scenario of the stroke of an externally installed oil cylinder. When users are conducting the installation work, they have a great degree of autonomy and can accurately determine the installation and fixing position of the sensor by themselves according to the actual on-site situation. This characteristic is of great significance in actual operation and provides great convenience for users. It is particularly worth mentioning that if the on-site conditions permit, users do not even need to drill holes in the oil cylinder body. They only need to skillfully connect and install the sensor with the corresponding mechanism of the oil cylinder displacement, and the entire installation process can be successfully completed. This installation method is not only convenient and fast, but also easy to disassemble during the subsequent maintenance process, which greatly saves the time and labor costs required for installation and maintenance. From the perspective of the actual application effect, the oil cylinder stroke detection system constructed through this installation method has demonstrated extremely high stability and maturity. Long-term operation data shows that the sensor can continuously and accurately feedback the oil cylinder stroke information, providing a solid guarantee for the stable operation of the equipment. At the same time, considering its comprehensive performance in terms of installation convenience, maintenance simplicity, and long-term reliable operation, this installation method has outstanding cost-performance advantages. Compared with the installation methods of other similar products, it has achieved a more efficient and stable oil cylinder stroke detection function with a lower overall investment, effectively creating considerable value for users and has already become an ideal choice for the application of oil cylinder stroke detection in many industrial fields.
