The WRP eddy current crack detectors are used to determine cracks, overlaps, notches, pores, to
find voids on or just below the surface and to detect weld seams in metallic materials.
Built-in device
Table-top device
The eddy current crack detectors from LAW NDT are available in two versions. On the one hand as table-top devices, for manual testing, random sample testing, laboratory work and experiments. On the other hand, as built-in devices for integration in test systems for automated 100% quality control in the production line.
The WRP is available with one to four channels as standard. The basic version consists of a housing, a power supply unit for the internal power supply, an oscillator plug-in unit with power probe driver stage, digital measurement data acquisition and evaluation, a BUS system with free spaces for later channel expansion, signal and stroboscope outputs for display of measurement curves and fault localization on the test part as well as an Interface with a potential-free output for automatic part sorting.
The scope of delivery includes all connection cables for additional devices, a 1.8 m long PVC probe cable with single-core shielding and self-locking precision connectors. The table housing can also be equipped with a lockable hinged cover, and the probe cable is available with a steel jacket to protect against mechanical damage with an oil-repellent PVC coating. The devices can also be expanded to include features such as rotation monitoring and distance compensation.
