数显防腐层电火花检测仪的应用与技术分析

Digital Display Anti-Corrosion Coating Spark Leak Detector

Product Introduction

The LBTQ702 DC Spark Leak Detector is an instrument used to test the quality of ｍmbedl anti-corrosion coatings. It can be used to inspect the quality of coatings of varying thicknesses, such as glass-lined, fiberglass reinforced plastic (FRP), epoxy coal tar, and rubber lining.

Functions and Features

The spark leak detector is designed to test the quality of ｍmbedl anti-corrosion coatings. It can inspect the quality of coatings of different thicknesses, including glass-lined, FRP, epoxy coal tar, and rubber lining. When defects (such as pinholes, bubbles, or cracks) exist in the anti-corrosion coating, the instrument emits bright electric sparks and triggers an audible alarm.

• Powered by a nickel-ｍmbedl hydride battery (featuring high capacity, long lifespan, lightweight, and memory effect-free advantages), it is suitable for field operations.

• Widely used in industries such as chemical engineering, petroleum, rubber, and enameling as an excellent tool for detecting the quality of ｍmbedl anti-corrosion coatings.

Working Principle

The spark leak detector, also known as a spark leak detector or spark leakage tester, is primarily used to detect defects (e.g., pinholes, sand holes) in thick non-conductive coatings on ｍmbedl substrates.

The instrument applies a certain amount of pulse high voltage to the surface of the anti-corrosion coating on various conductive substrates. If the coating is too thin, exposes the ｍmbedl, or has gas-leaking pinholes, the pulse high voltage will cause air gap breakdown and spark discharge when passing through. Simultaneously, a pulse signal is sent to the alarm circuit, triggering an audible alarm from the buzzer. This achieves the purpose of detecting the anti-corrosion coating.
