Shengli SL-ⅢA|B Electrical Spark Leakage Detector

【Function and Purpose】

    Shengli SL- electrical spark leakage detector is a dedicated device to test the construction quality together with micropores and air gaps due to aging and corrosion of coatings on such metal surfaces as oil and gas pipelines, cables, enamels, metal tanks, and ship hulls.

    It complies with the national standard GB7993 and the German standard D2N51163.

【Characteristics】

1. Low power consumption, small volume, less weight

2. Easy, audible and visible, and convenient in operation

3. Pointer on the meter indicating the output voltage and the supply voltage.

【Primary Technical Parameters】

1. Measuring range: type A: 0.03-3.50mm; type B: 3.50-10.0mm

2. Output high-voltage: type A: 0.50-20.0KV; type B: 15.0-36.0KV

3. AC supply voltage: 220V±5

4. Built-in DC power supply: type A: 6V; type B: 8.4V

5. DC power consumption: 5W

6. Alarm delay: 1-2 seconds

7. Main frame volume: 228×85×180mm3

8. Main frame weight: 2.5kg (battery included)

【Detection Principles and Methodology】

    Principle: The resistance and the air gap density are very small at under coating, metal-exposed, and leakage micropores on the anti-corrosive and insulative coating of metal pipes, so when the high voltage passes through, the gap breakdown forms to generate spark discharge, giving out a pulse signal to the alarm circuit, and the alarm sounds with light. That’s how the spark detector conducts leakage detection on the anti-corrosive coating.

    Notes: Shengli SL-68 pipeline electrical spark detector is applicable if a digital-display high-accuracy electrical spark leakage detector is needed.
