Temperature Sensors - NTC Thermistors include different kinds of thermistors, and B57164K0471K000 is one of them. This article will talk about its application fields and working principle.

Application fields

B57164K0471K000 can be used in many application fields. Here are some examples.

• Temperature measurement: This type of thermistor is commonly used in various environment temperature monitoring systems to help sense temperature values precisely.
• Medical devices: It is suitable for heart rate monitors and oximeters used in the medical industry.
• Consumer electronic devices: It is also used to detect electromechanical sensors in modern smart devices.

Working principle

The B57164K0471K000 is based on the principle of a negative temperature coefficient (NTC). This means that the internal resistance of the thermistor decreases with the increasing temperature. This circuit is the typical circuit with a resistor and a thermistor in it. When the circuit is closed, electricity only flows in one direction, which is called a series circuit. The current in this circuit follows Ohm\'s law:

where I is the current, U is the voltage, R is the resistor and T is the temperature.

At RT, the resistance of the thermistor is R_T, and the current can be measured. As the temperature is changing, the resistance of the thermistor will also change. The current will be adjusted, and then we can calculate the temperature based on the original curve.

Conclusion

The B57164K0471K000 thermistor is an inexpensive and effective tool for temperature measurement, and its application fields vary from medical device to consumer electronic device. By measuring the voltage and the internal resistance, we can determine the temperature.
