Temperature Sensors – NTC Thermistors

NTC thermistors are temperature sensing components that have a negative temperature coefficient, meaning that their resistance decreases with increasing temperature. NTC thermistors are commonly used in applications such as temperature measurement, temperature control, inrush current protection, and power supply fault detection. B57164K0472K000 is a commonly used NTC thermistor.

Application Field of B57164K0472K000

The main application field of B57164K0472K000 is temperature measurement and control. Temperature measurement applications can be found in a wide variety of industries such as automotive, robotics, HVAC systems, medical and industrial control systems. The thermistor can be utilized as a temperature sensor to measure temperature in liquid, gas, and air. B57164K0472K000 is also used in temperature control systems. This thermistor can be used to turn on or off a heat source based on the temperature such as in HVAC systems.

Working Principle of B57164K0472K000

The B57164K0472K000 is an NTC thermistor which means its resistance decreases as the ambient temperature increases. This thermistor’s resistance at 25°C (77°F) is 472KΩ and its resistance at 100°C (212°F) is 56KΩ. The resistance decreases dramatically as the temperature increases, with the rate of change in resistance being determined by the thermistors B value. The B value of the B57164K0472K000 is typically 3380K.The working principle of the B57164K0472K000 is based on the fact that its resistance decreases as temperature increases. In a temperature measurement application, the thermistor is placed in the environment to be monitored, and the resistance of the thermistor is measured with a resistor. The measured resistance value can then be used to calculate the temperature inside the environment.In a temperature control application, the thermistor can be used to switch on or off a heat source based on the temperature inside the environment. If the thermistor detects an increase in temperature, the resistance decreases, and the thermistor triggers a switch. Depending on the power supply voltage of the system, the switch can be a relay, a transistor, or any other type of switch.

Conclusion

B57164K0472K000 is a commonly used NTC thermistor that is used for temperature measurement and temperature control applications. Its main application field is in a variety of industries such as automotive, robotics, HVAC systems, medical and industrial control systems. The thermistor works by having a negative temperature coefficient, meaning that its resistance decreases with increasing temperature. In addition, the B value of the thermistor is 3380K determines the rate of change in resistance with temperature. Thus, the B57164K0472K000 is a highly accurate and reliable NTC thermistor designed to survive harsh industrial environments.
