远传压力表的压阻比例系数检定方法探究

Remote Piezoresistive Gauge Scale Factor Test Method of Inquiry

在现代工业生产中,远传压力表是工艺测试和自动控制、保护系统中常用的压力仪表之一,但对这种仪表的检定方法,还没有计量检定规程加以规范。本文根据远传压力表的使用情况,提出压阻比例系数的检定方法,并与传统检定方法比较,分析其优势。

In modern industrial production, is one of the commonly used remote pressure gauge pressure gauge testing and automatic control technology, the protection system, but this method of testing instruments, there is no verification procedures to be regulated. Based on the use of remote pressure gauge, the proposed test method piezoresistive coefficient of proportionality, and compared with the traditional test methods, analyze their strengths.
