Working Principle
The detector applies pulse pressure to conductive substrates with insulating coatings. When defects like pinholes or cracks are present, the high voltage causes spark discharge at the gap, triggering the alarm circuit. This acousto-optic alarm system enables precise identification of coating quality issues.
