Alphagage+ Corrosion HIDDEN

Overview

Dual element transducers have a transmitting element and separate receiving element located side by side, the use of Pitch & Catch reduces any measurement problems which may result from material surface issues.

This product is a key tool to inspect ageing assets and solve problems in many industries but especially, Oil & Gas or Petrochemicals.

Typical applications include:

  • Metal pipe works
  • Pressure vessels
  • Structural parts
  • Storage tanks

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.

AlphaGage+ Standard Features

  • Echo-to-Echo functionalities
  • Up to 27 Hour battery life (high-capacity re-chargeable battery pack via the USB port)
