摘要
基于罗斯蒙特核级压力变送器的测试原理,从理论上提出了一种更加精确的变送器校验方法,即"零点调整法".使用该方法可以通过简单的计算后得到零点电流或者满量程电流的历次调整对变送器量程和零点的影响,实现了变送器不间断调整,为现场试验提供极大的理论支持,大大缩短了试验工期.同时,变送器的调整过程以经验为主的过程,深入到了理论计算的方式,也极大地降低了对现场试验人员经验的要求.
Abstract
Based on the testing principles of Rosemount's nuclear grade pressure transmitters,a more accurate calibration method called the'Zero Adjustment Method'is theoretically proposed.By employ-ing this method,one can determine the impact of consecutively adjusting either the zero current or the full-scale current on the transmitter's range and zero point via straightforward calculations,thereby en-abling continuous adjustment of the transmitter,offering significant theoretical backing for field tests,and substantially reducing the duration of these tests.At the same time,the adjustment process of the transmitter to experience-based process,in-depth to the theoretical calculation of the way,but also greatly reduces the field test personnel experience requirements.
