Temperature Sensors - NTC Thermistors

A NTC thermistor, such as the B57561G1103H000, is a temperature sensor comprising a negative temperature coefficient (NTC) thermistor. It is used in systems to measure and regulate temperatures in demanding applications with a high level of accuracy and repeatability.

Application Field

NTC thermistors are temperature sensing devices commonly used in a wide range of applications and industries such as:

• HVAC systems
• White goods and household appliances: dishwashers, washing machines, tumble dryers, ovens, etc.
• Condition control systems
• Medical and laboratory equipment
• Telecommunication stations
• Industrial control systems
• Vehicle/Automotive cooling systems
• Aerospace and aviation

Each application requires a specific type of thermistor, depending on different criteria, including temperature range, resolution, accuracy, environmental suitability, longevity and cost.

Working Principle

NTC thermistors suffer a small resistance change in response to temperature changes. The B57561G1103H000 thermistor includes a voltage output which is dependent upon the thermistor’s temperature, so the device is easy to use in a wide range of temperature measurement applications.

By using the thermistor’s resistance-temperature characteristics, an oscillator circuit consisting the thermistor and an RC network (Resistor Capacitor) can be used to generate a signal with very low temperature sensitivity. This signal is then converted into a stable temperature output voltage.

The choice of resistance-temperature characteristics depends upon the application and a variety of coefficients are available for different applications. However, the B57561G1103H000 is a popular choice in many applications due to its high precision and temperature stability capabilities.

Conclusion

The B57561G1103H000 NTC Thermistor is used in a number of applications as a temperature sensing device. Its high precision and temperature stability capabilities make it a popular choice in many applications due to its ability to accurately measure temperatures.
