The working principle of NTC thermistor in the control system.Automatic machine mirror

　　NTC thermistor is one of the most commonly used thermal components for the internal temperature measurement of the device. When the thermal resistance is used in the control system, it becomes a small and important part of the large system. The temperature controller is used to display the temperature detected by the thermistor. Once an accurate reading is obtained, the NTC thermistor will tell when the cooler or heater is turned off or opened to keep the appropriate temperature of the sensor.

　　The work of the temperature sensor is to send accurate temperature feedback to the temperature controller. Basic current flows through the NTC thermist resistance component, and the thermistor transmits the data to the temperature controller through the method of changing resistance. The changes in the resistance value are converted to voltage changes so that the controller can read them. The controller is considered to be the brain of the system. It obtains temperature information from the sensor and compares it with the temperature requirements of the device (setting value). Thermal resistance is used to change the temperature to match the setting point.

　　The position of NTC thermistor in the system may change the design of the controlled system. In order to obtain accurate results, NTC thermistor should be placed near the device that requires temperature control. If possible, NTC thermistor resistance should be embedded in the device Of course, sometimes it can be fixed with hot glue or paste to fix them for more convenient use.
