Abstract

According to the measurement precision requirements during geothermal testing process, optimize the circuit design and segmented curve fitting were used discussed the feasibility of realize high precision temperature detection. Platinum resistance were used as temperature sensing element, matched with high precision constant current source bridge in order to improve the precision of the hardware and the quadratic polynomial fitting and cubic polynomial fitting were analyzed and compared. Final experimental results show that the system made up the deviation intermediate detection process and achieved the purpose of high precision testing.
