(Summary description)　　As we all know, the application of temperature sensors is very wide, so in the automotive industry, its assembly, what has changed?   　　Install temperature sensors on buses to prevent spontaneous combustion 　　During the high temperature in summer, spontaneous combustion of buses often occurs. How to prevent spontaneous combustion of buses is also extremely important. In order to prevent problems before they happen, the Taiyuan City Bus Company in Shanxi has installed temperature sensors for some buses to ensure the safety of buses. 　　Generally speaking, spontaneous combustion accidents of buses are not unrelated to the long operating life of the vehicles and the aging of internal lines. In general, vehicles with a long operating life and rear-engined vehicles are prone to excessive temperature in the engine compartment and cause fires and other accidents during operation. 　　It is difficult for drivers of rear-engined vehicles to find problems such as excessive engine temperature, so installing a temperature sensor to give an alarm can play a greater role. The bus company installs temperature sensors on some buses. When the engine temperature reaches a set threshold, it will automatically alarm. The installation of temperature sensors can effectively improve various potential safety hazards of the engine, thereby ensuring the safety of driving and the personal safety of passengers. 　　New energy vehicles: energy saving and emission reduction 　　At present, "energy saving and emission reduction" is one of the main directions of global industrial development. On the one hand, it refers to the need to continue research and development of "energy saving and emission reduction" technologies for internal combustion engines; on the other hand, it refers to the need to strengthen the development of new energy vehicles. 　　The sensors used in hybrid/electric vehicles mainly include sensors for detecting battery temperature, temperature sensors for monitoring motors, and temperature sensors for battery cooling systems. The battery of a hybrid/electric vehicle can only provide the best energy output at a precisely defined operating temperature. Therefore, it is required to reliably monitor and adjust the battery temperature to prevent the battery from overheating and maximize its working life. At present, most hybrid/electric vehicle battery designs use NTC temperature sensors to measure their temperature. 　　Electric motors are another basic component of hybrid/electric vehicles. In order to ensure the long life of the motor and its best performance, the temperature of the electric motor also needs to be continuously monitored, and it is as accurate as possible to work in the temperature range above 140℃, so it is also very important to determine the temperature of the stator winding. , This is the only way that the motor can take full advantage of its advantages without the risk of overheating. In order to measure the temperature of the stator, it is also required that the sensor should be easy to install, and to ensure that the sensor is protected from mechanical pressure during installation and operation and has a high dielectric strength. The latter can prevent the driver current circuit from the measuring current circuit. Flashover phenomenon. 　　In addition, in practical applications, since the battery and driver are also important safety components of hybrid/electric vehicles, the reliability and shock resistance requirements of the sensor are also high, which requires the selection of electronic components, process and reliability verification Start with other aspects to provide the best comprehensive solution.     　　Due to the importance of sensors in electronic control systems, in a sense, the competition of advanced cars is the competition of sensors, and countries all over the world attach great importance to its theoretical research, new material application, and product development. 　　The Firstrate temperature sensor has a built-in high-performance digital circuit, which is carefully designed for the working conditions of radio frequency, electromagnetic interference, and surge voltage. It has the characteristics of strong anti-interference ability, wide power supply range, and polarity protection. It conforms to IEC, CE (EMC) ) Standard, with anti-radio frequency and electromagnetic interference. A precise conversion circuit is used to convert the resistance signal into a standard current, voltage or digital signal. 　　The Firstrate temperature sensor has an exquisite structure, the probe and connector are made of 316L stainless steel, and the shell is made of superb laser welding. The overall structure meets the IP65 standard (up to IP68), and has the characteristics of fast response, high accuracy, and long-term stability. , It is suitable for the temperature detection of liquid and gas, and meets the needs of aerospace, military industry, engineering machinery, automobile industry, air
