Temperature Sensors - PTC Thermistors

Temperature sensors come in many varieties, and the use of a PTC thermistor is one of the more popular options. PTC stands for positive temperature coefficient, and refers to the property of the thermistor\'s resistance increasing as temperature increases. The KTY82/252,215 is one example of a popular PTC thermistor. In this article, we\'ll take a look at the application field and working principle of the KTY 82/252,215.

Application Field

The KTY82/252,215 is a popular PTC thermistor used for temperature sensing applications. It has a wide range of temperature detection capabilities, ranging from -30 to +110°C. It has a thermal time constant of approximately 9 seconds in still air, making it suitable for applications which require quick response times. It can also withstand pressure up to 600 Vdc and has an operating current of ≤ 75 mA, making it suitable for use in a wide range of electrical applications. It is also used in a variety of medical applications, including temperature measurement and providing protection against overheating and current overload.

Working Principle

The working principle of the KTY82/252,215 thermistor is simple. It utilizes a semiconducting material that is sensitive to temperature changes, and its resistance will increase as the temperature increases. This increase in resistance is known as the positive temperature coefficient (PTC). As the temperature increases, the resistance will increase proportionately, allowing for the accurate measurement of temperature.When an electrical device is powered, the current will flow through the thermistor and its resistance will limit the current flowing through it. As the temperature increases, the resistance of the thermistor will increase, thus limiting the current flowing through it. This limitation in current prevents the device from overheating and ensures safety for the user and the environment.

Conclusion

The KTY82/252,215 is an example of a popular PTC thermistor, and its application field and working principle are both essential to understand when it comes to temperature sensing. The thermistor has a wide temperature range and is suitable for a variety of applications, including temperature measurement and electrical protection. Additionally, its working principle is relatively straightforward, and it utilizes a semiconducting material to detect changes in temperature and subsequently limit the current flowing through the device. As a result, it can be used to prevent overheating and ensure user safety.
