AlphaGage+

Precision and Corrosion Gauge


Ultrasonic Thickness Gauge

The AlphaGage+ is a key asset for inspectors, maintenance operators and QA technicians looking to measure essentially any engineering material thickness as it combines years of ultrasonic R&D into an extremely rugged and perfectly ergonomic hand held enclosure.

The AlphaGage+ is a very versatile piece of equipment, capable of performing integrity assessments of metal steel works affected by corrosion or erosion processes as well as to measure precisely the thickness of a critical piece of equipment.

All versions of the AlphaGage+ are supplied with a number of accessories including plastic carrying case, AC power adaptor, USB cable and certificate of calibration. Dependent on the version, the AlphaGage+ is also supplied with a suitable transducer for performing either Precision thickness measurements or for Corrosion measurements.


Core Features

  • Simply brilliant user interface design
  • Ergonomic enclosure & accessories
  • Fast Min/Max mode at 25 Hz
  • Large hi-resolution LED backlight
  • Colour screen or vibration alarms
  • Multiple sizes reading display
  • Custom design for IP67 rating
  • Up to 27hr continuous operation
  • Re-chargeable via USB port


Field Upgradable

The AlphaGage+ is can be used as either/both a precision thickness gauge and/or a corrosion thickness gauge. The AlphaGage+ is also upgradable in the field - A flexible solution as it can be fully loaded from the start or upgraded anytime later by easily activating its valuable software options when required.


Precision Gauge

Precision gauges are particularly effective when using single element transducers and delay line wedges in Pulse-Echo configuration to achieve higher accuracy than corrosion gauges and meet very strict quality control requirements.

Standard features include a wide thickness range (up to 20” in steel), a 1 micron resolution (0.0001” or 0.001 mm), store and recall up to 2,700 setups, a high end 30 MHz bandwidth instrument and a “Zoom Auto Tracking” functionality.

Standard AlphaGage+ C includes:

  • Access to single element probe database.
  • One DLK1025 transducer - 10 MHz, 0.25" diameter with Lemo to Microdot cable 6"

​ 


Typical Precision Gauge Applications

  • Use in the Aerospace, Automotive and Manufacturing sectors
  • Castings & turbine blades
  • Plastic parts
  • Coil steel & auto body panels
  • Fiberglass & gel coatings
  • Velocity Measurement
  • Aluminium, glass, ceramics & zinc


Corrosion Gauge

Without being limited to, the corrosion gauges generally use dual element transducers in a Pitch & Catch configuration to reduce surface problems and measure accurately the remaining wall thickness of metal structures subject to corrosion.

Standard features include a wide thickness range (up to 23” in steel), coating thickness and substrate thickness displayed simultaneously on gauge with live waveform, temperature correction and file compare features for data logger versions.

Standard AlphaGage+ C includes:

  • Access to dual and single element probe database.
  • One DKS-537 transducer - 5 MHz. .375" diameter transducer with potted cable


Typical Corrosion Gauge Applications

  • Use in the Power Generation, Oil &Gas and Service sectors
  • Pipes & Boiler tubes
  • Pressure vessels
  • High temperature applications
  • Storage tanks
  • Ship hulls
  • Steel beams


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.


Data Logger (B-Scan)

With internal SD card memory of up to 32GB, store without limit thickness readings with ID location for corrosion mapping or profile assessment and send readings to Microsoft ExcelTM (DataXLS) for further asset maintenance evaluation.

  • Datalogger functionalities
  • B-Scan (time based)
  • Temperature correction

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.

  • Live A-Scan
  • Positive/Negative/Full signal rectification
  • Adjustable range
  • Temperature correction
  • Coating thickness

Versions Available

  • AlphaGage+ C - High performance hand-held CORROSION thickness gauge.
  • AlphaGage+ P - High performance hand-held PRECISION thickness gauge.
  • AlphaGage+ CP - High performance hand-held CORROSION & PRECISION combined thickness gauge.

Additional add-on software options available on all models:

  • Data Logging (DL)
  • Waveform (W)

​For example the AlphaGage+ C is suitable as just a reliable corrosion gauge. While a AlphaGage+ CPDLW is a dual purpose corrosion and precision thickness gauge with A-Scan and B-Scan functionality.
