Abstract

The article presents an intelligent temperature transducer (ITT), which can work with a two-wire or a three-wire platinum resistance temperature detector (RTD). The ITT design allowed for compensation of the RTD's lead wire resistance. The ITT used the author's auto-calibration procedure, which minimized linearity errors of the ITT and RTD processing characteristics, ITT offset and gain errors, and errors resulting from changes in the ITT operating conditions concerning the nominal conditions. The presented results of a simulation and experimental studies confirmed the high effectiveness of this procedure. The determined uncertainty of temperature measurement using the Monte Carlo method and the obtained experimental results confirmed the possibility of measuring temperatures in the range of 0-200 °C with an expanded uncertainty of 0.02 °C at a 99% confidence level.

摘要

本文介绍了一种智能温度传感器（ITT），它可以与两线制或三线制铂电阻温度探测器（RTD）配合使用。ITT的设计考虑了对RTD引线电阻的补偿。ITT采用了作者的自动校准程序，该程序将ITT和RTD处理特性的线性误差、ITT失调和增益误差以及ITT工作条件相对于标称条件变化所导致的误差降至最低。仿真和实验研究给出的结果证实了该程序的高效性。使用蒙特卡洛方法确定的温度测量不确定度以及获得的实验结果证实了在0至200°C范围内进行温度测量的可能性，在99%置信水平下扩展不确定度为0.02°C。
