In addition, NXRT15WF104FA5B040 is ideal for use in applications involving short-term temperature measurement/control, long-term temperature measurement/control, single point temperature measurement, multiple points temperature measurement, and rapid temperature variation.

Working Principle

The NXRT15WF104FA5B040 NTC thermistor is based on a physical property of materials known as temperature coefficient of resistance. This refers to the fact that the resistance of certain materials changes in proportion to a change in temperature. The NXRT15WF104FA5B040 NTC thermistor is composed of a specifically formulated ceramic material which displays a predictable electrical resistance to temperatures ranging from -30°C to 105°C.

The change of resistance versus temperature value is determined on an individual component basis and identified by its R–T curve. This curve is calibrated against a calibrated thermometer or electronic circuit, and then nominative characteristics are determined according to user requirements.

The calibration process is known as TCR (Temperature Coefficient of Resistance) calibration. Based on the known parameters, it is possible to calculate the NTC thermistor’s resistance value at a given temperature by using Ohm\'s law. This makes it possible to measure/control/annunciate temperatures with precision, long-term stability, and high reliability.

Multiplying the TCR value of the NXRT15WF104FA5B040 NTC thermistor with the measured temperature and subtracting it from the written nominal value, it is possible to calculate its resistance value at any given temperature. Thus, resistance can be used to measure temperature.

Conclusion

The NXRT15WF104FA5B040 NTC thermistor is a temperature sensor that is useful in many different applications. Its working principle is based on the temperature coefficient of resistance of the specifically formulated ceramic material that it is composed of, and its resistance can be calculated at any given temperature by using Ohm\'s law.
