Introduction

Temperature Sensors - NTC Thermistors are thermally sensitive resistors whose resistance at any given temperature is measured. Thermal sensing and control systems are required in many applications, such as medical equipment, home appliances, heating and cooling systems, and industrial process control. The NTC thermistor is an object of choice for temperature sensing and control. TC502J2K is a next-generation thermistor temperature sensor, which can be used to accurately measure and sense temperature in various applications.

Application Field

TC502J2K is capable of measuring temperatures for a range of -40ºC to +125ºC, and its temperature accuracy is ±0.5ºC. This makes it suitable for a variety of hot spot applications, such as in the HVAC, automation, and industrial sensing sectors. It is commonly used in monitoring and controlling temperature in refrigerators, air conditioners, electric ovens, emitting and switching devices, and motor protection applications. Also, It can be used to sense and control the critical temperature data in medical and laboratory applications where accuracy is of utmost importance.

Working Principle

The TC502J2K is constructed with a Next-generation thermistor element which is composed of metal oxide in the core of the thermistor, surrounded by outer layers of glass and metal. When the TC502J2K senses changes in temperature, the thermistor’s resistance increases or decreases accordingly. This is due to changes in the electrical charge of the surface of the metal oxide core. The TC502J2K thermistor is then connected to a circuit with an adjustable voltage divider, allowing the thermistor to measure the temperature from the voltage that is measured. The voltage is then converted from analog to digital, and this value is further digitalized by the microprocessor. The data is sent to a controller (or a microprocessors) that adjusts the parameters of the environment or the device in order to achieve the desired temperature.

Conclusion

TC502J2K is a versatile next-generation temperature sensor, suitable for many thermally sensitive environments. It is accurate and reliable, and offers a wide range of temperature measurement and control. With its range of -40ºC to +125ºC and ±0.5ºC accuracy, it can be used in medical and laboratory applications, HVAC, automation, and industrial sensing applications. The working principle is based on electrical charges being converted from analog to digital, and then read and adjusted by a microprocessor.
