绝压、负压变送器的调校及使用

Calibration and Use of Absolute Pressure and Negative Pressure Transmitter

本文解决了在校准小量程绝压变送器时,因设备问题造成线性差的问题,在设备受限的情况下负压变送器的校准及在实际使用中绝压及负压变送器应该注意的事项。

This article provides the solution of avoiding linear variable difference while calibrating small-scale absolute pressure transmitter,provides the solution of how to calibrate negative pressure transmitter with limited equipment,and brings up the points of attention while practicing absolute presure and negative pressure transmitters.
