General Information

For Inspection of SG/Ductile or Gray Iron Parts and In-Line Nodularity Control the “MATVEL” is a comprehensive solution featuring Dry-Coupled Probes and Direct Read-out of Velocity with User-Programmable Thresholds. MATVEL can run up to 8 Channels and has 5V / 24V Inputs & Outputs with the option of Ethernet communications.

MatVel is a state-of-the-art digital ultrasonic nodularity control system for industrial applications in the cast iron industry; uniquely offering dry coupled ultrasonic measurement capability.

The system is suitable for manual or in-line spot testing of components. This is achieved by using a customized transducer and delay line.

MatVel combines all the functionality of an outstanding flaw detector together with specific add-ons customized for the application.

The system can therefore meet the requirements for any set up, with live A-scan signal presentation and direct reading of acoustic velocity, thickness measurements and flaw (in spot) detection.

MatVel is an autonomous system ready for the integration on the most common process lines as one additional step or to be installed in a separate inspection cabinet.
