Alphagage+ Precision HIDDEN
The Sonatest AlphaGage+ instrument uses single element transducers in Pulse-Echo configuration in order to measure to higher accuracy than corrosion gauges.
Overview
This is often required to meet very strict quality control requirements such as experienced in the Aerospace and Automotive industries.
With a wide offering of quality probes, delay line wedges and software options, the Sonatest precision gauge offering is very versatile.
Typical applications include:
- Steel
- Aluminium
- Glass
- Plastic
- Rubber
Features
True Thickness (under coating)
When a metal surface is protected by anti-corrosion paint or coating, true wall thickness measurement using Echo-to-Echo function is a key feature and available on all AlphaGage+ models.
Field Upgradable Features
Upgradable in the field, the AlphaGage+ is a flexible solution as it can be fully loaded from the start or upgraded anytime later by easily activating software options when required.
Data Logger (B-Scan)
Thickness readings with ID location for corrosion mapping or profile assessment and send readings to Microsoft Excel™ for further asset maintenance evaluation.
Live Waveform (A-Scan)
Display live A-scan for echo verification and real time control of acoustic range, rectification, gain and blanks or combine the A-Scan with B-Scan view for even more detailed analysis.
Oxide Scale (Boiler Tube)
Simultaneously display the boiler tube wall thickness as well as the internal oxide scale thickness at their velocities greatly improves the efficiency of investigation to extend tube life.
