NTC Thermistors: Application Field and Working Principle

A Negative Temperature Coefficient (NTC) thermistor is a type of temperature sensor, typically a ceramic thermistor, which has a resistance that decreases with temperature. NTC thermistors are often used to measure temperature or detect its change, detect over-heating situations, and many other temperature-dependent applications that require precision. The operating temperature range for the NTC thermistor typically ranges from -50°C to 150°C, with typical values of -45\u00B0C to 125\u00B0C depending on the type of thermistor. NTCC200E4472JT, which is a NTC thermistor, typically comes in a variety of characteristics, rated at 2, 4 or 5 Watts, and is typically supplied in a 12mm or an 20mm case size. This thermistor is composed of a metal-encapsulated disc which helps in providing superb mechanical strength and vibration resistance, as well as temperature performance characteristics. The metal-encapsulated disc houses a nickel-plated copper pin and a ceramic disc that is painted with an NTC glaze. The metal components provide a path for current through the NTC thermistor which can be measured accurately.The NTC thermistor changes its resistance depending on the ambient temperature which is measured by the thermistor. For an NTC thermistor, the resistance decreases with increase in temperature. When a voltage is applied to an NTC thermistor, an electric current flows between the two points of contact. The voltage and the current through the NTC thermistor are related by an equation known as the Steinhart-Hart equation. This equation defines the relationship between the thermistor resistance and the thermistor temperature. Since its resistance changes with temperature, an NTC thermistor can be used to detect temperature. This is done by measuring the resistance of the thermistor and then calculating the temperature. The Steinhart-Hart equation can be used to calculate the temperature using the measured resistance. Owing to its temperature response, reliability, and accuracy, NTC thermistors have a wide range of applications in the industrial, automotive, electronics, and medical sectors. Some of the common applications of NTC thermistors are temperature control, protection against over-heating, over-voltage protection, engine protection, etc. They are used in control systems to change the speed of electrical motors, ovens, heating systems, and many more applications.Some of the major advantages of NTC thermistors are their high accuracy in temperature sensing, temperature and moisture resistance, and long-term stability. They are also available in wide range of sizes, shapes, and operating temperatures. Moreover, NTC thermistors are relatively inexpensive and easy to install.In conclusion, NTC thermistor is one of the most accurate types of temperature sensors and can be used in a variety of applications where accurate temperature measurement is required. They are reliable, long ­lasting and cost effective. The NTCC200E4472JT thermistor is a great example of a NTC thermistor which offers the highest accuracy and precision in temperature sensing.
