Thermistor can be used as an electronic circuit component for instrument circuit temperature compensation and thermocouple cold junction temperature compensation, etc. The self-heating characteristic of NTC thermistor can be used to realize automatic gain control, forming an RC oscillator amplitude stabilization circuit and a protection circuit.
When the self-heating temperature is much higher than the ambient temperature, the resistance value is also related to the heat dissipation conditions of the environment. Therefore, the thermistor is often used in flow meters, gas analyzers, and thermal conductivity analysis to make special inspection components. PTC thermistors are mainly used for overheating protection of electrical equipment, non-contact relays, constant temperature, automatic gain control, motor startup, time delay, color TV automatic degaussing, fire alarm and temperature compensation.
The role of thermistors in the circuit of different products:
Micro-Wave Oven
Thermistors are used in microwave ovens and machines to determine and maintain the internal temperature. Without the thermistor in the microwave oven, overheating may occur in the unit. This may cause a potential fire.
Circuit Protector
The power source or surge protector in your home or office also uses a thermistor. Without thermistor in such products, the amount of surge will be uncontrolled. This may cause overheating or too much power plugging into the devices, which may cause short circuits in some of your electronic devices.
Car
Cars, trucks and buses all use thermistors. They are used to determine the temperature of oil and ice refrigerant. This is how you can know if your car is overheating. The thermistor is connected to the indicator on the vehicle dashboard. The thermistor in the car cannot be blocked or adjusted. Instead, they are used to gather information. This allows drivers to repair their car or truck before a serious accident occurs.
Thermistors are used in many fields other than the fields mentioned above. With the rapid development of science and technology, the application field of thermistor is also expanding. To purchase thermistors, you must choose a regular manufacturer.
