1Manufacturer of pulse spark leak detectorsummary:

The AT-11Z digital pulse spark leak detector is assembled and debugged from high-quality imported industrial grade electronic components. An instrument used to detect the quality of metal anti-corrosion coatings. This instrument can be used to perform quality testing on coatings of different thicknesses, such as enamel glass, fiberglass, epoxy coal tar, and rubber lining. When there are quality issues with the anti-corrosion coating, such as pinholes, bubbles, and cracks, the instrument will emit bright electric sparks and sound an alarm. Due to its use of nickel hydrogen batteries for power supply (which have the advantages of high capacity, light weight, no pollution, no memory effect, and can be quickly charged and discharged, making it an ideal green environmental product), it is particularly suitable for field operations. This instrument is designed to be advanced, stable and reliable, and can be widely used in industries such as chemical, petroleum, rubber, enamel, etc. It is a tool for detecting the quality of metal anti-corrosion coatings.Manufacturer of pulse spark leak detectorFeatures: Adopting digital circuit control and pulse generation principle* The single key switch automatically enters the charging state during charging, and the digital circuit structure makes the indication more stable and the detection of high-voltage pulses more stable. The aluminum alloy casing makes the whole machine more beautiful, sturdy and durable.

The device is equipped with an intelligent trickle charger, which not only has fast charging speed but also enables the battery to reach a good saturation state, resulting in longer battery life and usage time. When charging, please turn off the instrument for charging. During the charging process, the red light of the charger flashes to indicate that it is charging. When the charger changes from flashing red light to constant green light, it indicates that the charging is complete.

3、 Shandong pulse anti-corrosion coating electric spark leak detector, AT-11Z type detection principle and structural description

1. Detection principle: The electric spark detector applies a certain amount of pulse high voltage to the surface of various conductive substrate anti-corrosion layers. If the anti-corrosion layer is too thin, leaks metal or has gas leakage pinholes, when the pulse high voltage passes through, it forms a gap breakdown and generates spark discharge. At the same time, it sends a pulse signal to the alarm circuit, causing the alarm to sound an alarm, thus achieving the purpose of detecting the anti-corrosion layer.

2. Structure description: The instrument consists of three main parts: the host, the high-voltage probe, and the probe.

(1) Host part: equipped with integrated control circuit, sound alarm device, etc. The names of the front, back, and board components of the host are shown in Figure (1) and Figure (2), respectively.

(2) High voltage probe section: equipped with a high voltage generator, high voltage output button switch, and lead wires. The names of each component of the high-voltage probe are shown in Figure (3).

(3) Exploration section: There are two types of probes: straight probe brush and flat probe brush.

4、 Operation steps:

1. Before operation, it is necessary to familiarize oneself with the names and functions of each component.

(1) High voltage indicator: Its value directly indicates the output high voltage (KV).

(2) Function selection switch: It has three functions: working, off, and charging.

(3) Battery undervoltage indicator light;

(4) High voltage adjustment knob: Adjust the strength of the high voltage output to meet the needs of different anti-corrosion layer inspections.

(5) High voltage probe connection socket: used to connect the high voltage probe and the host part.

(6) The grounding socket is used to connect the grounding wire.

(7) Alarm hole: Whenever high voltage sparks are generated, an audible alarm will sound;

(8) Fuse: The power fuse is 2A.

(9) Probe connection terminal: used to connect various probes.

(10) High voltage switch: Only by turning on this switch can high voltage be generated.

(11) Handle: Hold this handle with your hand during detection.

(12) High voltage probe connection plug: This plug is connected to the host socket.

(13) Connect the cable.
