摘要
介绍了内嵌压力源式自动压力校验系统的组成、主要功能和特点.该系统可精确、快速、稳定、无超调地产生校验压力仪表所需的标准压力值,其精度为0.05%FS.并且,该系统能按照压力仪表的检定规程在全量程范围内对其进行正、反行程的压力逐点自动校验.此外,还可根据具体的校验条件修改校验量程、校验点数、压力设定值等参数.当压力仪表为压力变送器时,可对输出的电信号进行测量和显示,且与上位机结合能实现校验数据结果处理和自动生成校验报告等功能,从而显著地提高了校验工效.
The composition,main functions and features of automatic pressure calibration system with pressure source inside were introduced.This system could produce standard pressure at the accuracy grade of 0.05%FS accurately,quickly,stably and no overshoot for calibrating the pressure instruments.And according to the test procedures of the pressure instruments,this system could calibrate the pressure of the pressure instruments point by point in the full scale.Depending on the specific calibration conditions,this system also adjusted the calibration range,the number of the calibration points,pressure settings and other information.When the pressure instruments were pressure sensors,this system could measure and display their output signals.And it can be combined with the host computer to realize processing the calibration data and then generating calibration report automatically to improve the calibration efficiency significantly.
