APSL313Automatic Standard Pressure Generator Control Function Tester

Product Overview

Automatic standard pressure generator control function tester according to the national metrological verification regulationJJG1107-2015specifications, composed of high-resolution measurement sensor, acquisition system, and display. For0.01class of inspected automatic standard pressure generator, the sampling frequency is10Hz; for0.02the sampling frequency of the tested automatic standard pressure generator at level and below is20Hz. Automatically test parameters such as overshoot or undershoot, control stability, duration, response time, and control static error of the automatic standard pressure generator.

Automatic test process

1) Stop state: set value is "0", controller is empty

2) Press the "Start" key, set value is the first point, send the set point to the controller, causing the controller to start pressurizing, during the pressure stabilization process record: overshoot (return) amount, upon receiving the controller stabilization signal or pressing "Stable” key to start recording stability and duration.

3) After the test is completed, press the “Set Value Increase” key to set the second point, causing the controller to start pressurizing.During the pressure stabilization process, record: overshoot (or return) amount. If response time needs to be recorded, when the controller stabilizes, press the “Stable” key to start recording control stability. If duration needs to be recorded, record it.

4) Repeat 3) until the upper range limit.
