FIBER OPTIC VACUOMETER A general description of vacuum metrology

光纤 真空 计真空计量概述

The vacuum measurement was realized by using ZDF-5427M vacuometer and the accuracy was 3 % FS .

真空测量采用 ZDF-5427M微机型复合 真空 计，其由热 偶 计和热阴极电离 计复合而 成，该 真空 计测量控制精度为3%FS。

Compound vacuometer must be able to realize intelligent switching among sensors and intelligent switching among different ranges of one sensor in the measuring progress .

复合 真空 计在测量过程中除能实现传感器间的智能切换 外，还要能实现同一种传感器的不同量程间的智能切换。

And also introduce simply communicating with PLC Data Display Device and Thermocouple Vacuometer .

同时简要介绍了与PLC、数字显示 表以及热偶 真空 计 的 串行通讯。

For enlarging the measuring rang we can spread 2 kinds or 2 kinds above the sensor compound usage and realize the intelligent switching among sensors thus we can use one set compound vacuometer to account the vacuum that can immediately carry out big scope to measure .

为了扩展测量范围，可将两种或两种以上的传感器复合使用，并实现传感器间的智能切换，从而使用一台复合 真空 计即可实现大范围的真空测量。
