NTC thermistors are temperature sensors that have been widely used in industrial applications due to their simplicity, reliability, and cost efficiency. The B57561G1103F005 is a NTC thermistor that has a variety of application fields and a distinct working principle.

Applications

The B57561G1103F005 is specifically designed to be used in thermostats, motor protection, building automation, and temperature-based sensing applications. As this thermistor is highly temperature sensitive, it can detect temperature changes accurately with which a variety other sensors are unable to compete. Additionally, the B57561G1103F005 has low power consumption, which is an advantage over other thermistors as it ensures longevity and works under low power conditions.

Working Principle

The working principle of the B57561G1103F005 is based on the standard NTC thermistor. A temperature sensitive resistance is situated in the thermistor, and this resistance will change as soon as the temperature is varied. It is this change in resistance that determines the output of the thermistor. The most common type of NTC thermistor, like the B57561G1103F005, uses the following formula to convert resistance to temperature:

T = B/[In(R/R_ref)+lnA]

Where:

T is the temperature in °C,

A is the material constant,

B is the temperature coefficient in °K,

R is the resistance in Ohms,

R_ref is the reference resistance in Ohm.

This NTC material is preferred as it works with small signals and gives a very wide range of sensing temperatures.

Conclusion

The B57561G1103F005 is a NTC thermistor, whose application fields include thermostats, motor protection, building automation, and temperature-based sensing. Its working principle is based on the standard NTC thermistor, which uses a temperature sensitive resistance to measure temperature changes. It is this resistance which is used to calculate the temperature using the formula T = B/[In(R/R_ref)+lnA].
