Latest generation Eddy current testing 08 June 2022

The ELOTEST PL600 from Rohmann, combines testing for cracks and heat treatment, as well as testing for material mix-up and grinding burn, so that a single testing instrument is sufficient for a wide range of applications in several stations.

In particular, in fully and semi-automated production lines, different materials testing processes take place at the same time. Whereas parts have to be tested for differences in hardness at the beginning, they may have to be tested for cracks in the downstream production process. For this purpose previously, several instruments were integrated into the line. The modular design of the PL600 makes it possible to combine testing for cracks and heat treatment. The instrument is fully integrated into the line by wide ranging I/O functions with a fieldbus connection.

The EloLine software, which is used during the testing of long products, has also been developed by Rohmann GmbH. It serves to visualise 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 database. 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. Today, with more than 70 employees, the family run company in Frankenthal, Germany, 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.
