Introduction

Temperature Sensors - NTC Thermistors play an important role in providing temperature measurement solutions in various fields of application. The ABNTC-0805-103J-3950F-T sensor is a commonly used NTC thermistor, and requires understanding of its application field and working principle for effective usage.

Application Field

ABNTC-0805-103J-3950F-T temperature sensors are widely used in temperature measurement and control. Its use includes adjusting heat and cooling in system processes, industrial automation, and even medical applications. It can be seen in applications such as temperature sensing in steam distribution systems, refrigerator compressors, small electric motor control, etc.

Working Principle

The working principle of ABNTC-0805-103J-3950F-T temperature sensors is based on the change of resistance with temperature. These sensors are constructed from a special type of ceramic material, which exhibits a negative temperature coefficient, meaning that the resistance decreases when the temperature increases. The temperature is sensed by connecting an electrical current to the thermistor and then measuring the resulting voltage drop over the sensor. The amount of voltage drop is directly proportional to the temperature.

The Temperature Sensitivity Curve

The ABNTC-0805-103J-3950F-T temperature sensors have a temperature sensitivity curve that is defined by its resistance versus temperature (RvsT) characteristic. The curve is obtained by measuring the resistance of the thermistor at different points between 50C and 250C. By plotting the resistance versus temperature data, a characterised curve is obtained. This characterisation curve is used to calibrate the sensor so that when using the sensor in an electronic circuit, the temperature can be deduced.

Calibration and Linearity

The ABNTC-0805-103J-3950F-T temperature sensors can be further calibrated to obtain a more linear response to temperature changes. Once the temperature sensitivity curve has been obtained, a calibration algorithm can be applied to the data to obtain a much more linear response.

Temperature Hysteresis

The temperature hysteresis of ABNTC-0805-103J-3950F-T temperature sensors can also be measured and compensated for. Hysteresis is the relationship between the temperature measured when a certain current is applied, and the temperature measured when the same current is removed. The hysteresis error of ABNTC-0805-103J-3950F-T temperature sensors is typically very low, but can be further reduced by proper calibration.

Conclusion

In conclusion, the ABNTC-0805-103J-3950F-T temperature sensors can be effectively used to measure temperature in numerous applications. It\'s working principle is based on an NTC thermistor, which exhibits negative temperature coefficient behaviour. The sensor is calibrated to obtain a more linear response and can have its temperature hysteresis error reduced with proper calibration.
