Whether crack detection or material mix-up, “Elotest PL600” displays the test results of different testing stations, which in the past required several devices along the line. In so doing, it is convincing by its user friendliness and its unsurpassed signal purity. The modular concept for testing long products together with the licensing system for the Elotest PL600 allow for a short change-over time, a straightforward exchange of the testing techniques and an upgrade of the eddy current testing instrument, which is possible at any time. Elotest PL600 has been supplemented by a 19‘‘ (PL600/R) and a compacter 9.5‘‘ (PL600/RC) remote version for integration into automated systems.

The “Elo Line” software, which is used during the testing of long products, has also been developed by Rohmann. It serves to visualize and record the acquired results. Serial part numbers, batches, serial numbers, length of the tested parts and the name of the inspector can for example be saved in the data base. A detailed test report for every tested part or a report on a specific production batch can of course be printed out.

Rohmann not only develops and manufactures testing instruments, but also the pertaining testing technology such as rotors, yokes, coils and sensors. The customers are furnished with customized solutions from one provider. Today, with more than 70 employees, the family run company is a competent and reliable partner, from the first feasibility study to making an offer and also with its support during the commissioning process as well as training.
