Fast Temperature Measurement Method Combining Data Acquisition with Analytical Calculation

A fast temperature measurement method by equal interval data collection and calculation of three points was put forward.The method combines data acquisition with analytical calculation.Firstly temperature value of the temperature sensor was collected at three moments on equal time interval,and then the medium temperature to be measured was obtained through analytical calculation.The method has less data collection points.Analytical calculation is simple and rigorous.It can be realized easily in the measurement system based on microprocessor or signal processor,and can avoid the error factors existed in other measurement methods based on complex principle and algorithm.The measuring speed of the method depends on the electrical properties of the system,and has no correlation with the thermal inertia of the sensor.It is suitable for various contact type temperature sensor to measure various medium temperature.
