Crack inspection and sorting with ELOTEST PL650 06 May 2025

Rohmann GmbH offers various solutions for the non-destructive testing of materials for fastener and fixing technology, including the digital inline test instrument ELOTEST PL650, which can be applied for the automated structure inspection of screws and bolts, nuts, rivets and punched parts. 

With the High Distance Sensor (HDS), developed for this purpose, and the FastSort software, also by Rohmann, more than five hundred parts per minute can be inspected for defects in structure. The sensor is designed so that, with the high penetration depth of up to 10mm, it is possible to penetrate a glass plate to carry out sorting checks. Therefore, the sensor can simply be mounted underneath a glass plate, on which the test parts are placed.

Whether crack detection or material mix-up, the eddy current test instrument ELOTEST PL650 displays the test results of different testing stations, which in the past required several devices along the line. Application specific user interfaces also simplify the operation of the ELOTEST PL650. Test results are displayed with unmatched signal quality and signal-to-noise ratio, with exceptional system and sensor monitoring ensuring ultimate reliability. 

The modular design of the ELOTEST PL650 facilitates the combination of various inspection tasks within a single instrument for a wide range of applications. ELOTEST PL650 has also been supplemented by a 19 inch (PL650/R) and a compacter 9.5 inch (PL650/RC) remote version for integration into automated systems.
