Online Pinhole detection: High-voltage Film Continuity Tester

Pinhole detection: High-voltage Film Continuity Tester Performance Characteristics of Product ◆Reference executive standard for pinhole detection: High-voltage Film Continuity Test Method in GB4074.5-2008/IEC60851; ◆To detect pinhole and particles (enamel tumor) on surface of enameled wires of different wire sizes and shapes in the production line; ◆Fully computer-controlled, Windows XP Chinese operation interface, a host is capable of controlling 96 routes of enameled round wires or 48 routes of enamel flat wires; ◆Two networking modes (wire or wireless transmission) is optional based on user’s actual production environment, facilitating system upgrade and expansion; ◆Facilitate circuit detection, provide mature software design, high accuracy and easy operation; ◆High detection sensitivity, durable and no damage to test samples; ◆Particle and pinhole detection can be conducted by the same detection head; ◆Each detection head can perform such functions as pinhole counting, particle counting, pinhole acousto-optic alarm and continuous defect (bare wire) acousto-optic alarm, timely and clear reporting defect location; ◆All records of each detection head are automatically stored in the database and when detection is not stopped, can be viewed at any time and the query results be printed; ◆It supports full-automatic detection, wire change clearing and wiring length calculation can be interlocked with enameling machine without requiring additional operation.
