Abstract :
In embedded-distribution control system, the analogue signal under test is usually non-linear. Differential median calibration method based on four-wire platinum resistance temperature compensated constant current source is proposed in accordance with the characteristics of temperature control in the course of beer fermentation. This method can guarantee accuracy of temperature detection in a small temperature range, has an edge small amount of work, rapid detection, low-cost and high-precision. The method provide a viable solution for the detection of small-scale non-linear analog.
