程控式真空规校准装置主要用于日常对工作用真空规的校准。它采用动态直接比对法、静态膨胀法和静态直接比对法等三种方法可以对１×１０５～５×１０－４Ｐａ范围内的真空规进行校准。采用可编程控制器对校准全过程实行自动控制，并具有保护、报警、语音提示等功能，提高了工作效率和安全可靠性，避免了由于误操作或真空系统故障造成的经济损失。
Programmable vacuum gauge calibration device is mainly used for routine calibration of vacuum gauge. It adopts the dynamic direct comparison method, the static expansion method and the static direct comparison method and other three methods to calibrate the vacuum gauge in the range of 1 × 105 to 5 × 10-4Pa. The programmable controller realizes the automatic control of the entire calibration process and has the functions of protection, alarm and voice prompts to improve the working efficiency and safety and reliability and avoid the economic loss caused by misoperation or vacuum system failure.
