Porosity Holiday Detector,Metal Surface coating leak detection,DC Pulsed Holiday Detector

Function and use:

SL-III series electric spark detector for the detection of oil and gas pipelines, cables, enamel, metal storage tanks, lining anti-corrosion, hull and other metal surface anti-corrosion coating construction quality and aging corrosion point.When the anti-corrosion coating has microholes, air gap and other quality problems, the instrument will emit bright sparks, and produce sound alarm.The instrument design is novel, easy to operate, widely used in petroleum, chemical, rubber, enamel, power plant and other industries, is a necessary testing tool. SL-III Porosity Holiday Detector is a special testing equipment used to detect oil and gas pipelines, cables, enamel, metal tank, hull and other protective coatings flaws. It is a simple and practical equipment.

[Detection principle and method]

The metal surface insulation anticorrosive layer is too thin, the resistance value and the air gap density are very small, when there is a high voltage through the formation of air gap breakdown and spark discharge, to the alarm circuit to produce a pulse signal, the alarm sends out acousto-optic alarm, according to this principle to achieve the purpose of anticorrosive layer leak detection.
