Everything Eddy Current

Products

Maxwell PECT

ETher NDE represent globally the Maxwell NDT pulsed eddy current technology (PECT) product.

With unbeatable inspection capability and a truly simple user interface, we challenge you to test the Maxwell system side by side against any other PEC system and prepare to be surprised!

A no nonsense, capable and flexible PEC inspection tool which has been developed for harsh industrial environment inspections as well as applications in splash zones, subsea inspections and ROV deployments.

Pulsed Eddy Current (PEC) is an inspection technique for inspecting carbon steel objects such as pipes and vessels, without the need for contact with the steel surface. PEC can measure percentage variations in steel thickness through any non-conductive and non magnetic materials between sensor and surface such as air, insulation material, concrete, plastics, coatings, sea water and marine growth, paint, deposits, oil, composite repairs, fireproofing, “scabs” aluminium sheeting and other non-magnetic insulation covers; so ideal for Corrosion Under Insulation (CUI) applications. Previous instruments often lacked the power to be fast and effective.

Using the latest battery technology, MAXWELL NDT introduces a novel and very powerful PECT instrument with a design based on 25 years’ hands-on experience at a global Oil Company.

Industries & Applications

Advantages

  • Large range in wall thickness, up to 65mm (2.5") and  insulation thickness combined, hence well suite to vessel inspection not just piping/pipelines.
  • Maximum Lift-Off range is 0 – 250 mm (0-10”).
  • A maximum surface temperature of up to 550°C (1020 °F).
  • Superior signal to noise ratio.
  • Extremely robust design delivers outstanding performance under the typical rigours associated with on-site inspection.
  • Standard set is splash water tight, salt and fog resistent, meets IP65.
  • Intuitive software has been developed with the NDT technician in mind, fast data collection, real time data analysis, simple reporting on-board the instrument and on your desktop PC.
  • Excel format data provides easy compatibility with other applications.
  • No hidden costs - all inclusive lifetime pricing means no annual software support fees.

Features

Inspection Ready 

The set is splash water tight, robust and easy to operate. Data collection is fast (two measurements per second) and has a scanning mode. Two cables, length 8m (26ft), is included in the standard kit. Up to 100m (328ft) can be provided.

Probes

There are four standard probes, each for a different lift-off range. The probes are optimized for defect sensitivity.  Underwater probe sets are available  covering different depth rating and lift-off ranges.

Data output

Colour-coded wall thickness readings are displayed on the touch screen display during data recording.
A MS-Excel field report can be produced quickly by the tablet computer. In addition, PC-based software is provided for further analysis and reporting.

Portable Power

Fast and reliable PECT measurements require a high-energy magnetic pulse, which is delivered by a dedicated powerful battery inside the data acquisition unit. The tablet computer is powered by two separate batteries. Both type of batteries are provided with external chargers and are hot-swappable.
