Introduction

Temperature Sensors - NTC Thermistors, often called thermistors, are widely used in many applications as precise temperature sensors. Specifically, the NB20N50104KBA Temperature Sensor is a commonly used thermistor and the purpose of this paper is to discuss the application fields and working principle of the NB20N50104KBA.

Application Fields

The NB20N50104KBA has multiple application fields, including automotive, medical, industrial, and consumer products. In the automotive industry, the NB20N50104KBA is typically used for controlling the engine’s temperature. It helps to regulate the engine’s coolant levels and alert the driver of any over-heating issues. The NB20N50104KBA can also be used as part of the engine’s fuel and air management system, helping the engine to operate within its optimal temperature range. In the medical industry, the thermistor is used in medical equipment for monitoring body temperature in patients. This allows medical staff to identify a potential fever and act accordingly. The NB20N50104KBA is also used in automated medical products, such as defibrillators, to help regulate temperature levels and potentially save lives.In the industrial sector, the NB20N50104KBA is used to measure and regulate extreme temperatures in industrial processes. This helps to ensure that machinery is operating at safe temperatures and can assist in identifying potential sub-optimal performance.In the consumer products sector, the NB20N50104KBA is used in many consumer appliances and electronic products. This includes cooling systems, space heaters, and air conditioners, which require precise temperature regulation to work properly.

Working Principle

The NB20N50104KBA is an NTC (negative temperature coefficient) thermistor, which means it has a decreasing resistance as the temperature increases. NTC thermistors are composed of two wires, each of which has a specific resistance. As the temperature rises, the resistance of one of the wires decreases, while the resistance of the other wire increases, resulting in a net decrease in resistance. The thermistor works by measuring the exact amount of voltage that passes through the thermistor’s two wires. This type of thermistor is also capable of measuring higher temperatures than PTC (positive temperature coefficient) thermistors, making it useful in more extreme temperature applications.

Conclusion

The NB20N50104KBA Temperature Sensor is a commonly used NTC thermistor with multiple application fields. It is typically used in the automotive, medical, industrial, and consumer product industries. The thermistor works by measuring the voltage passing through the two wires and is capable of measuring higher temperatures than other types of thermistors.
