WRP crack detecting devices
The WRP eddy current crack testing devices are used to detect cracks, overlaps, notches, pores, to find voids on or just below the surface and to detect weld seams in metallic materials.
Product
LAW NDT’s eddy current crack testing devices are available in two versions. On the one hand, as table devices, for manual testing, random testing, laboratory work and experiments. On the other hand, as built-in devices for integration into testing systems for automated 100% quality control in the production line.
Built-in device
Tabletop device
The scope of delivery includes all connection cables for additional devices, a 1.8 m long PVC probe cable with individual wire shielding and self-locking precision connectors.
The table housing can also be equipped with a lockable hinged lid and the probe cable is available with a steel jacket to prevent mechanical damage with an oil-repellent PVC coating. The devices can also be expanded to include features such as rotation monitoring and distance compensation.
Performance data
On/Off –
Elimination of interference on the sensor
Slow / Normal / Fast –
Adaptation of the measured value acquisition to the relative travel speed between the probe and the test part
0 – 100 % –
Amplification of the measured input signal of the crack detection probe
20 KHz / 50 KHz / 80 KHz –
Test frequency to adapt to the test criteria of the test part
Internal / External –
Internal: Measuring cycle activation when the probe approaches the test part
External: Measuring cycle activation via a machine control from outside
Good / Reject –
Visual display of the test result after each measuring cycle with automatic control of the potential-free contact for parts sorting
Status display indicating that the distance between the probe and the test part is too large, as well as an error message if the sensor is interrupted or defective

WGP structural testing devices
The WGP-AVF-01 structural testing device is a reliable, tried-and-tested device for a quick evaluation of structural differences, material mix-ups, hardening depths, etc..
In addition, different probes and coils can be connected to ensure high flexibility and therefore cost-effectiveness.
The structural testing device is recognized worldwide in the automotive industry and its suppliers, both because of its high repeatability and because of its easy handling.
Application
For test criteria such as material mix-ups or different hardening depths, the high throughput speed is ideal for sorting screws, balls, needles, camshafts, etc. The device has been industrially tested in a wide range of working conditions and can be operated both automatically and manually. In addition, different probes and coils can be connected to ensure high flexibility and therefore cost-effectiveness.
Key Features/Benefits:
- User-friendly: Setting and adjustment effort is minimal and very easy to repair thanks to our plug-in card system.
- Adaptable: For coils, the fill factor can be neglected over a wide range. Probes do not require direct contact with the material.
- Flexible testing: Laboratory and production equipment can test a wide variety of parts by connecting a probe or a toroidal coil. The WGP-AVF-01 has an adjustable test frequency of 100Hz - 10KHz. It allows the analysis of individual problems in the laboratory as well as a wide range of test parts for rapid use in the production line.
Accessories
Probes
The LAW NDT probe program includes a variety of sensors for a wide range of applications, which essentially differ in diameter, housing shape, connection plug and measuring characteristics.
Screwable DIN and push-pull connectors in industrial quality, combined with stainless steel adapter sleeves, guarantee contact reliability and longevity. High flexibility thanks to different housing and shaft lengths for tight installation spaces, as well as 45° and 90° flattened probes for inclined positioning on test parts, round off the program.
Coils
Since a wide range of testing tasks must be covered in materials testing today, LAW-NDT has developed a variety of different test coils and probes that are used in hardness testing, structural testing, weld seam detection, layer thickness measurement and other applications.
Depending on the task, you can choose between round coils, rectangular coils and test probes, each in different sizes, in order to achieve the best possible test results. As with all LAW-NDT products, you will also find the tried and tested screwable DIN and push-pull connectors in industrial quality. Their use guarantees contact reliability and longevity.
Test coil housings from LAW-NDT are provided with appropriate threaded holes and enable safe installation and a tight fit in the test field.
Cable
The LAW-NDT probe cables form the interface between the test sensor and the evaluation electronics. They usually have to withstand harsh environmental conditions. Good shielding and mechanical strength are the prerequisites for interference-free signal transmission.
That is why we offer liquid and chemical-protected sheathing as well as highly flexible probe cables covered in steel braid with very tight bending radii for production use. Our range of cables includes lengths from 0.5m to 20m with straight and angled connectors that can be used for all LAW-NDT sensor types.
Specific spare parts
We know that every minute is money. Since a short response time is always important, LAW NDT has created processing machines and capacities in the main factory so that we can produce most of the custom-made products ourselves. Play it safe with LAW NDT!
