With the rapid development of electronic technology, NTC temperature sensors are widely used in various fields, such as smart home, office automation equipment, industrial equipment, new energy vehicles and so on. Due to its wide range of applications, NTC temperature sensors are also required to be able to adapt to various environments and temperatures, especially in high humidity and high temperature environments. Therefore, a NTC temperature sensor with high water and oil resistance is needed.
However, the existing temperature sensors with high water and oil resistance have shortcomings. On the one hand, the metal shell is used to protect the head and it is not suitable for installation in small spaces; on the other hand, the epoxy resin has low performance in preventing liquid penetration, resulting in The glass-sealed thermistor temperature sensor and the wire can not be used in water or oil, and the epoxy resin and the wire insulation layer cannot be completely fused, which also makes the temperature sensor not suitable for liquid temperature measurement.
Therefore, domestic sensor manufacturers have developed a high-water-proof and oil-proof NTC temperature sensor that can be used in harsh environments such as high temperature and high humidity. It uses a high-precision single-ended glass-sealed thermistor, and the two leads of the thermistor are connected by cold pressure The feet are connected to two wires respectively, which also helps to reduce the volume of the temperature sensor. The temperature sensor can be completely put into water or oil to work normally, and can work normally in a high temperature environment above 250℃ for a long time, and the size of the temperature sensor can be made within 1.5mm, which requires extremely large installation space. Low. It has the advantages of small size, suitable for installation in a small space, and high performance of preventing liquid infiltration.
