| Abstract: | view of the problem that some power generation enterprises ignore the accuracy of temperature measuring elements, this paper proposes high precision temperature measuring elements should be adopted in the heat supply trade or the other important parameters measuring instruments, thus to improve the accuracy of power plant measurement. Also, some views on the calibration method of armoured thermal resistance, the application value of copper resistance and the cancellation of intermediate temperature measuring links in DCS etc. are put forward. |
