Lingee Foseek NTC Thermistor Applications

The NTC thermistor is widely used in temperature measurement and control circuits, with its electrical and mechanical properties being better than that of other types of temperature sensors. Therefore, the application of NTC thermistor can greatly improve the precision of temperature measurement and control system. In this article, the author introduces the basic characteristics of NTC thermistor and its applications in some temperature measurement circuits, and further expands its application fields and scope.

First, let's introduce the basic characteristics of NTC thermistor. The resistance of NTC thermistor changes as the temperature changes, which is inversely proportional to the resistance value of the object under test. In addition, its resistance change rate is greatly superior to that of other temperature sensors, which can meet the requirements of high-precision measurement and control. In addition, its small size, light weight and good stability make it widely used in electronic equipment and precision instruments.

Secondly, let's introduce the application of NTC thermistor in some temperature measurement circuits. For example, in the constant temperature control circuit of the electronic oscillator, NTC thermistor is used to measure the temperature of the oscillator and adjust the output frequency of the oscillator by controlling the current of the electronic heater. In this way, the temperature of the oscillator can be accurately controlled to ensure the accuracy of the output frequency. In addition, in the circuit of the human body's temperature measurement and display instrument, NTC thermistor is used to measure the body temperature, and then convert it into digital signal for display by using AD conversion circuit. This can improve the precision and accuracy of the body temperature measurement.

Finally, let's expand the application fields and scope of NTC thermistor. In addition to being used in temperature measurement circuits, NTC thermistor can also be used in other fields. For example, it can be used in intelligent control systems to achieve accurate temperature measurement and control; it can also be used in environmental monitoring to monitor the temperature of air conditioning rooms and refrigerators; it can also be used in medical equipment to monitor the vital signs of patients; it can also be used in automobile electronics to monitor the engine oil temperature and water temperature.

In short, NTC thermistor is widely used in temperature measurement and control circuits because its electrical and mechanical properties are better than that of other types of temperature sensors. It can greatly improve the precision and accuracy of temperature measurement and control system. In addition, its small size, light weight and good stability make it widely used in electronic equipment and precision instruments. In addition to being used in temperature measurement circuits, it can also be used in other fields such as intelligent control systems, environmental monitoring, medical equipment and automobile electronics.
