美国ROSEMOUNT 3095MV型智能流量变送器校验技术的研究

Check-Up of an Intelligent Flow Transducer ROSEMOUNT 3095MV

本文对美国ROSEMOUNT3095MV型智能流量变送器的校验问题进行了分析,提出一种采用外加压力源,精密电阻信号模拟温度输入的技术,以精密数字万用表,精密电阻箱,补偿式微压计,活塞式压力计为标准,HART275手操器为辅助来校验智能3095MV流量变送器的方案,并介绍了本方案的工作原理和校验方法,同时采用标准总不确定度分析的方法论述了所采用方法的可行性。

This paper proposes a check-up method for the intelligent flow transducer ROSEMOUNT3095MV.The system is composed of a pressure source, an accurate resistance signal to simulate the temperature input, a piston type pressure meter, and a HART275 hand operated device. A standard uncertain degree method is used to describe the feasibility of the method.
