Applications of NTC thermistors 1

An NTC thermistor is a temperature-sensitive electronic component whose resistance changes with temperature. It is widely used in various electronic devices and systems, such as temperature sensors like the TL431AIDBZR, thermostats, power supply circuit protection, motor protection, water heaters, ovens, toasters, induction cookers, and automotive electronic systems. diode

1. Temperature Sensor

As a temperature sensor, the NTC thermistor operates on the principle of measuring temperature by detecting changes in its resistance at different temperatures. The measurable temperature range can be determined based on the characteristic curve of the selected NTC thermistor. In practical applications, the NTC thermistor can be directly mounted on the surface of the object whose temperature is to be measured, and the temperature value can be read through a circuit.diode

The advantages of NTC thermistors as temperature sensors include their high accuracy, fast response speed, and low cost. They are widely used in fields such as household appliances, medical equipment, industrial automation, and automotive electronics.

2. Temperature Control

NTC thermistors can be used as temperature sensors in temperature controllers to achieve precise temperature regulation of the controlled object. For example, in a water tank heating system, an NTC thermistor is installed in the tank to control the water temperature. When the water temperature falls below the set point, the controller automatically activates the heater to raise the temperature. Once the water reaches the desired level, the controller shuts off the heater, maintaining the temperature stable near the set value.diode
