NTC Thermistors play an important role in sensing and controlling the temperature of a particular substance or object. Many industries incorporate NTC Thermistors in their production processes to ensure that all products are manufactured to the desired specifications. B57227K112J2 is an example of an NTC Thermistor, typically used for sensing the temperature of liquids. This article will focus on its application fields and how it works.

Application Field

B57227K112J2 is a precision temperature sensor designed for system temperature monitoring in heating, ventilation and air conditioning (HVAC) applications. It uses the resistance of a platinum doped ceramic chip to measure the temperature. The chip is able to precisely measure temperatures from -40°C to 250°C with a spot accuracy of 0.1°C. The sensor’s wide operating temperature range and range of form factors make it suitable for various industrial temperature measurement applications.

It is commonly used in industrial process control, switchgear monitoring, motor control, compressors, and brown goods. This type of thermistor is also suitable for air/water valves, defrost sensors, freezers, food service, medical and beverage dispensing, and wastewater management applications.

Working Principle

The B57227K112J2 contains a chip sensing element (thermistor) made of pure bronze doped with a small amount of platinum. This chip is encased in a ceramic moulding in order to ensure the highest levels of accuracy and reliability. The platinum doped ceramic material has a negative temperature coefficient (NTC) of resistance, meaning the resistance decreases as the temperature increases.

When the heat is applied to the sensor, the chip quickly responds and the resistance drops. The magnitude of the resistance change is proportional to the temperature shift and can be measured by connecting the B57227K112J2 to a voltage supply. The change in voltage can then be recorded and used to calculate the temperature.

Conclusion

In conclusion, the B57227K112J2 NTC Thermistor is an accurate, reliable and affordable temperature sensing solution for a variety of industries. Its wide application fields include HVAC, industrial process control, switchgear monitoring, motor control, compressors, air/water valves, defrost sensors, freezers, food service, medical and beverage dispensing, and wastewater management. Its working principle relies on the negative temperature coefficient of the chip sensing element, so that the change in voltage can be measured and used to calculate the temperature.
