Metallic Tubes (EMAT)

‍

Features

• Non-contact EMAT technique.
• Appropriate for all metallic materials.
• Probes for continuous measurement of materials up to 650⁰C.
• No-wear sensors that do not touch the material inspected.
• Great accuracy (+/-2.5µm) and lateral resolution (3mm).
• Sensor arrays and touch probes for continuous and spot measurements.
• 100% tube coverage option using proprietary encircling ring technology.
• Automatic calculation of eccentricity and ovality.
• Complementary sensors for measurement of shape and conductivity (in aluminum).
• Thickness measurement on internally tapered tubes.
