Temperature Sensors - NTC Thermistors

NTC thermistors, also known as negative temperature coefficient thermistors, refer to temperature sensors which use a negative temperature coefficient (NTC) to monitor a change in temperature within a given range. NTC thermistors must conform to IEC standards and be effective over a certain operating range. DC95F302VN is a specific model of NTC thermistor, and its application field and working principles will be explored in this article.

Application Field

DC95F302VN is an NTC thermistor designed for a broad range of applications. It can be used for a wide range of temperature-controlled processes, such as food processing and industrial appliances. Additionally, this thermistor can also be used to monitor the temperature of heating and air conditioning systems, often used in commercial and residential space. Microelectronic industry is an area in which the DC95F302VN NTC thermistor finds application. The thermistor is also suitable for application in other fields, such as household electrical devices and automotive electronics.

Working Principle

The DC95F302VN NTC thermistor works by changing the actual resistive value of the thermistor in response to external temperature changes. This process is known as temperature compensation. As the temperature increases, the resistivity of the thermistor increases. This increase in resistivity is known as a negative temperature coefficient (NTC). The resistive material of the thermistor is coated with a protective film, which will act as an insulator and further increase its operating temperature limit.When the temperature of the thermistor increases, its resistance decreases, and this resistance is what is responsible for regulating the temperature of the device in which it is installed. In order to measure the temperature with this thermistor, DC95F302VN is equipped with two pins which can be connected in a closed circuit. Connecting the first and the second pin allows a current to flow through the thermistor and the resistive material. As the temperature increases, the amount of current flowing through the thermistor will change. This current can then be amplified and measured accordingly. In short, this is how DC95F302VN NTC thermistor works.

Conclusion

The DC95F302VN NTC thermistor is suitable for applications in numerous fields. It uses a negative temperature coefficient to accurately measure temperature. When the temperature increases, the thermistor\'s resistance decreases. This process is known as temperature compensation. By measuring the amount of current flowing through the thermistor, the temperature can be measured accurately, allowing for precise temperature regulation.
