• Process status indication
• Strain gauge type vacuum digital transmitters

Theory of Working:

The leakage testing machine works basically on “Vacuum Decay” principle. Vacuum applied with preset value. The final differential vacuum is obtained after allowing sufficient time for the drift to stabilize and is therefore considered to indicate a true leak without noise. The pre-set value is calculated by subtracting the value B from the initial measurement A. this is the value used to compensate drift in subsequent tests. Indication feature The system memorizes various parameters setting by selecting channel such as OK/NG criteria and the duration of CHG, BAL & DET stages. These setting can be restored easily.
