【 Detection Principle and Method 】

principleThe insulation and anti-corrosion layer on the metal surface is too thin, and the resistance value and air gap density at the leakage iron and leakage micropores are very small. When high voltage passes through, air gap breakdown occurs, causing spark discharge and generating a pulse signal to the alarm circuit. The alarm emits an audible and visual alarm, achieving the purpose of leak detection of the anti-corrosion layer based on this principle.

Note: If you need a high-precision, digital display electric spark leak detector, you can choose“SL-68 type Pipeline electric spark detector.
