As an early temperature sensor manufacturer in China, the company has witnessed the development process of China's high-speed rail industry from scratch. It has become a qualified supplier for CRRC Tangshan, CRRC Changke, CRRC Qingdao Sifang Co., Ltd., CRRC Zhuzhou Electric Co., Ltd., CRRC Yongji Electric Co., Ltd., CRRC Sifang Co., Ltd., CRRC Qishuyan Co., Ltd., CRRC Dalian Locomotive Co., Ltd., Bombardier Co., Ltd., and Alstom Co., Ltd. Since 2006. Since 2006, we have successively developed and equipped traction motor, axle box, gearbox temperature sensors, as well as temperature vibration composite sensors and speed sensors for multiple unit CRH1, CRH2, CRH3, CRH380, CRH5, CR300, CR400, and intelligent multiple unit series models. The products launched in the early stages have been running for over 2.4 million kilometers without any faults. At the same time, we have collaborated with foreign enterprises such as Alstom and Bombardier to provide temperature sensors for traction motors of exported high-speed trains, achieving successful substitution of foreign products.

The company has always adhered to the concept of "honesty leads to prosperity, and wisdom leads to success". For many years, we have provided customers with excellent and reliable products, which have been widely recognized. In the future, we will continue to innovate and work with our customers to maintain stable development.
