NTC thermistors are thermistors, also known as negative temperature coefficient thermistors, that use a functional resistor made up of semiconductor material with a negative temperature coefficient. They are commonly used as temperature sensors for measuring and controlling temperature in many industrial and domestic applications. In this article, we take a closer look at the 202FG1K application field and working principle as well as some of its major features and applications.

202FG1K Application Field and Working Principle

The 202FG1K is part of NTC Thermistor’s 202FG series of thermistors, which are designed for high temperature and current resistors for temperature measurements and control. The 202FG1K is designed for accuracy over a wide range of temperatures and has a high dielectric breakdown resistance with minimal self-heating. It is a temperature sensor with a wide temperature range (-30C to +180C) which can measure temperatures from -45C to +200C. It has excellent repeatability, stability, temperature linearity, and long-term reliability over a wide range of temperatures. When measuring temperatures, the 202FG1K has a unique and fully temperaturized calibration to accurately detect and measure temperature changes while offering excellent stability under varying temperature conditions.

The 202FG1K has two distinct operation modes which are based on two different operating principles. The first is the direct current mode, which is suitable for applications that involve measuring temperature in a fixed range, has a fast response time and provisions for digital signal output with two-way power communication. This mode is often used for controlling temperature in manufacturing processes, such as in the food, beverage, chemical, and automotive industries. The second is a dual voltage supply mode, which is suitable for applications that involve measuring and controlling temperature over a wide range. This mode offers an analog signal output for easy integration into an application\'s existing electric circuits.

Features and Applications

The main feature of the 202FG1K is its high-temperature accuracy and long-term reliability. In addition, it also has improved stability and reduced power consumption, making it a desirable device for applications in harsh environments. Its accelerated aging is significantly lower than that of other thermistors which makes it an ideal device for extended use. Some of the common applications for the 202FG1K include temperature regulation in medical, industrial, and automotive applications, HVAC systems, process and environmental control, and various types of industrial and home appliance control systems.

In addition to its use in temperature regulation, the 202FG1K can also be used for over-temperature protection, current limit protection, and in pressure monitor systems with high-temperature ranges. Its robust design also allows it to perform efficiently and accurately in a wide range of weather conditions and varying operational temperatures, so it can be used in both outdoor and indoor applications. Its superior temperature range enables it to be used in over-temperature applications, such as in desiccators, industrial ovens, and cold rooms.

The 202FG1K is also used in medical applications, such as in operating rooms, imaging systems, and operating/rehabilitation chairs. Its exceptional temperature accuracy and reliability make it ideal for use in medical monitoring and surgical equipment, where accurate temperature measurements are essential to ensure best patient outcomes. Its fast response time and dual voltage supply also make it a perfect choice for temperature regulation in medical devices.

Conclusion

The 202FG1K is an excellent choice for accurate temperature measurement and control. Its excellent repeatability and stability at varying temperatures, long-term reliability, and fast response time make it an ideal device for many industrial applications. Its superior temperature range and robust design allow it to be used in both indoor and outdoor conditions. The 202FG1K is a popular choice for medical, industrial, and automotive applications due to its high accuracy and reliability.
