Description
technical field [0001] The invention relates to a circuit control device, in particular to a Pt100 thermal resistance sensor simulation device based on reverse design. Background technique [0002] Among many temperature sensors, Pt100 platinum thermal resistance sensor is a temperature sensor whose resistance value changes with temperature, and is an internationally recognized standard sensor for high-precision temperature measurement. The essence of temperature measurement with Pt100 platinum thermal resistance sensor is to measure the resistance of the sensor. Usually, the change of resistance is converted into analog signals such as voltage or current, and then the analog signal is converted into digital signal, and then the corresponding temperature is converted by the processor. Because Pt100 platinum thermal resistance sensor has the characteristics of high precision, good stability and reliable performance, it is widely used in industry. In the measurement environme...
