摘要
Abstract——During the operation of the target‑station water‑cooling system, considerable dispersion occurs in temperature readings from multiple platinum‑resistance thermometers under identical process conditions, resulting in severe absolute‑temperature distortion at some measuring points. This adversely affects equipment thermal‑state evaluation, heat‑load calculation, and over‑limit interlock protection. Through full‑chain error‑traceability analysis of the temperature‑measurement system, temperature distortion is found not to originate solely from degradation of the platinum‑resistance sensor itself. Interfacial thermal resistance introduced by installation‑heat‑transfer conditions and lead‑wire resistance imbalance caused by terminals in intermediate junction boxes constitute the major sources of on‑site additional errors. This paper elaborates the fundamental principles of platinum‑resistance temperature measurement, conducts theoretical analysis and quantitative calculation for sensor‑intrinsic error, installation‑heat‑transfer error, and signal‑acquisition‑loop error. Combined with comparison‑method calibration tests in a constant‑temperature bath, the contribution weight of each error source is analyzed, and the compensation boundary conditions for the three‑wire temperature‑measurement loop are clarified. Comprehensive engineering countermeasures are proposed from the perspectives of sensor‑calibration management, installation‑structure optimization, wiring‑process control, and operation‑maintenance system construction. The distinction between sensor‑body calibration and on‑site complete‑loop verification is emphasized, and implementable quantitative acceptance indices are provided. The research outcomes can serve as a reference for improving temperature‑measurement accuracy of water‑cooling systems and guarantee safe operation of cooled‑down equipment.
