    Spark Emission Detector

    Overview Standards Terms
    The spark detector generates electric sparks on the material surface through high-voltage electrodes to detect defects in insulating coatings or films. When a breakdown occurs at weak spots, the instrument triggers an alarm and records the location. It is used to identify issues such as pinholes and uneven thickness in materials like plastic films, rubber, and cable insulation layers.
    Selection
    When selecting a spark detector, consider the material type and thickness to determine the required detection voltage range. Choose the response frequency based on production line speed, and opt for a waterproof model in humid environments. The electrode shape should match the material surface, while also checking the alarm recording function and calibration convenience.
