A thermistor is a type of temperature sensor that exhibits a significant change in electrical resistance with a change in temperature. The term "thermistor" is a portmanteau of "thermal" and "resistor." These devices are designed to measure and respond to temperature variations.
There are two primary types of thermistors:
1. **NTC (Negative Temperature Coefficient) Thermistor:** NTC thermistors are the most common type. Their resistance decreases as the temperature increases. In other words, their resistance is negatively correlated with temperature. NTC thermistors are made of semiconducting materials and are typically composed of metal oxides.
2. **PTC (Positive Temperature Coefficient) Thermistor:** PTC thermistors, on the other hand, exhibit an increase in resistance with rising temperature. Their resistance is positively correlated with temperature. These are often made from ceramic materials and are used in applications such as overcurrent protection and self-regulating heaters.
The primary application of thermistors is temperature measurement and temperature compensation. They are used in a wide range of electronic devices and systems, including:
- Temperature sensors in thermostats and climate control systems.
- Temperature compensation in electronic circuits to stabilize components' behavior with varying temperature.
- Inrush current limiters for preventing high initial current when turning on devices.
- Temperature monitoring and control in industrial processes and equipment.
- Over-temperature protection in electronic devices.
Because of their small size, fast response time, and high sensitivity, thermistors are a popular choice for many temperature-sensing applications. They are often used in conjunction with external circuitry to convert the resistance change into a measurable voltage or current, allowing precise temperature measurement and control.
