Research on improving measurement accuracy of low temperature waste heat pump system of temperature sensor
Source abstract
Abstract
The problem is that the low temperature waste heat pump system for temperature measurement is not accurately measured. A method of improving measurement accuracy of the Pt1000 temperature sensor was proposed. First, the Pt1000 temperature sensor is date calibrated. Second, the least square method is used to fit the data of actual measurement. Finally, by using the principle of error evaluation, the most suitable corrective equation in the range of 10–100 °C for the Pt1000 temperature sensor was identified. Through actual verification, the calibration equation obtained by this method takes less memory space, has fast calculation speed and high accuracy in operation, and can effectively improve the accuracy of temperature measurement of the low temperature waste heat pump system.
