pt100 temperature sensor is a sensor that converts temperature into electricity by using the laws of various physical properties of substances changing with temperature. These physical properties exhibiting regular changes are mainly physical.

In recent years, the process of my country's industrial modernization and the continuous rapid growth of the electronic information industry have driven the rapid rise of the sensor market. As an important category of sensors, PT100 temperature sensor accounts for more than 40% of the total sensor demand. A temperature sensor is a semiconductor device that utilizes the resistance of NTC to change with temperature, and converts non-electrical physical quantities into electrical quantities, so that temperature measurement and automatic control can be performed. The temperature sensor has a wide range of uses, and can be used for temperature measurement and control, temperature compensation, flow rate, flow and wind speed measurement, liquid level indication, temperature measurement, ultraviolet and infrared light measurement, microwave power measurement, etc. It is widely used in color TV, Computer color monitors, switching power supplies, water heaters, refrigerators, kitchen equipment, air conditioners, automobiles and other fields. In recent years, the rapid growth of the automotive electronics and consumer electronics industries has driven the rapid growth of the demand for temperature sensors in my country.
