PTC thermistors were used as timers in the degaussing coil circuit of most CRT displays. This article defines describes thermistors thermal-sensitive resistors that respond to temperature changes permitting very precise temperature measurement and the use of temperature to control devices such as room thermostats or process controllers.
This article describes applications for the following purposes.

Digital thermometers thermostats Automotive applications to measure oil and coolant temperatures in cars trucks Household appliances like microwaves fridges and ovens Circuit protection ie. Surge protection Rechargeable batteries ensure the correct battery. Thermistors are used as temperature sensors.
They can be found in every day appliances such as fire alarms ovens and refrigerators. They are also used in digital thermometers and in many automotive applications to measure temperature. Thermistors derived from the term thermaIly sensitive resistors are a very accurate and cost- effective sensor for measuring temperature.
Available in 2 types NTC negative temperature coefficient and PTC positive temperature coefficient it is the NTC thermistor that is commonly used to measure temperature. The word thermistor is derived from a combination of the words thermal and resistor and they are typically used in commercial applications that include as but one example self-resetting protectors that sense when too much electrical power and heat enters a circuit. PTC thermistors were used as timers in the degaussing coil circuit of most CRT displays.
A degaussing circuit using a. We can also use PTC thermistors as heater in automotive industry to provide additional heat inside cabin with diesel. We can use PTC thermistors as.
A thermistor is a temperature sensitive resistor they are often used as a temperature sensor. The term thermistor is a contraction of the words thermal and resistor. All resistors have some dependency on temperature which is described by their temperature coefficient.
The main use of a thermistor is to measure the temperature of a device. In a temperature controlled system the thermistor is a small but important piece of a larger system. A temperature controller monitors the temperature of the thermistor.
It then tells a heater or cooler when to turn on or off to maintain the temperature of the sensor. Thermistors can be used in many ways enabling the temperature of the medium surrounding the device or the device itself to alter its resistance. This can then be detected by the equipment and used for everything from broad temperature sensing to overload cut-outs and many more ideas.
Thermistor Thermistors are used as temperature sensors for example in fire alarms. In the most common type of thermistor the resistance decreases as the temperature increases. While the principle use of thermistors are as resistive temperature sensors they can also be connected in series with another component or device to control an electrical current flowing through them.
In other words they can be used as a thermally sensitive current-limiting devices. Thermistors are also commonly used in modern digital thermostats and to monitor the temperature of battery packs while charging. Thermistors are often used in the hot ends of 3D printers.
They monitor the heat produced and allow the printers control circuitry to keep a constant temperature for melting the plastic filament. The measurement and the control of the temperature are the major applications of the thermistor. The thermistor is also used for various other applications which explain below in details.
Thermistor Sensor Applications for Temperature Measurement Compensation and Control NTC thermistor temperature sensors are used in a variety of thermistor senor applications to help regulate monitor control and compensate temperature. One of the properties of PTC thermistors is that when an excessively large current flows they generate heat by themselves and become highly resistive. With this property they are used as overcurrent protection devices.
This article describes applications for the following purposes. For inrush current limiting. This article defines describes thermistors thermal-sensitive resistors that respond to temperature changes permitting very precise temperature measurement and the use of temperature to control devices such as room thermostats or process controllers.
Thermistors are mostly used in digital thermometers and household appliances such as ovens and refrigerators and so on. Stability sensitivity and time constant are the general properties of thermistor that make these thermistors durable portable cost-effective highly sensitive and best for measuring single-point temperature. Thermistor probes can be used in automobile and truck tire curing as well as for monitoring and controlling engine temperatures.
They are even used in missiles and spacecraft. Some more potential equipment uses of NTC thermistor probes are for plastic laminating and hot glue as well as fire protection and safety.
