Crack-Check

MoviTHERM Crack-Check uses infrared non-destructive testing (irNDT) Vibro-Thermography to quickly identify cracks in metallic, ceramic, and composite materials. This turnkey Lock-in Thermography (LiT) system uses ultrasound excitation to induce friction at crack interfaces producing heat.

The system works with cooled and uncooled IR cameras with multiple lens configurations to meet various application requirements. The Crack-Check system can be configured for mobile, lab, and robot guided in-line applications.

Crack-Check Benefits

NON-CONTACT CRACK DETECTION

Active irNDT thermography “sees” various crack types in metallic, ceramic, and composite materials.

FLEXIBLE AND EXPANABLE

Upgrade a system by adding lenses, enclosures, stages, and IR cameras.

irNDT Made Easy

Complex analysis technology is simplified for dependable inspection results.

How does Crack-Check work?

Crack-Check uses ultrasonic frequencies to excite the specimen. The resulting friction between vibrating cracks creates heat signatures that are measured by the infrared camera. A computer captures multiple IR images and applies a processing algorithm to produce a surface map identifying localized hotspots.
