Maxwell PECT

MAXWELL PECT

The MAXWELL PECT instrument is designed for the inspection of carbon steel and low-alloyed steels, which are magnetic. For magnetic test specimens, the eddy currents are concentrated on the surface directly after the magnetic pulse. Subsequently, the eddy currents diffuse into the test specimen, until the backwall is “found”. This results in a characteristic shape A-scan: a straight line, corresponding to the diffusion of the eddy currents, followed by a curved section when the backwall is sensed.

OVERVIEW

Maxwell PECT  The PECT instrument comprises a ruggedized tablet computer connected to a data acquisition unit. The set is splash watertight, robust and easy to operate. Data collection is fast (two measurements per second) and has a scanning mode. The data is analyzed in real-time with various quality control features that assist the operator to correctly analyze the data.
There are four standard probes, each for a different lift-off range. The probes are optimized for defect sensitivity.
The instrument can either be operated from the probe and from the tablet computer.
PECT Probes
Color-coded wall thickness readings are displayed on the touch screen display during data recording. An MS-Excel field report can be produced quickly by the tablet computer. In addition, PC-based software is provided for further analysis and reporting. 
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 types of batteries are provided with external chargers and are hot-swappable.
  • Compact magnetic field and fast high energy pulse delivers an optimal signal to noise ratio
  • High range WT (2”/5cm) and insulation thickness, suited for vessels, not just pipework
  • Dedicated Pulse Power with hot-swap batteries
  • Robust and rugged design ideal for typical on-site conditions
  • Easy to use software: setup wizards, simple pdf/excel reporting, USB export
  • Rapid and reliable data collection, based on 25 years of experience of on-site operation
  • Desktop PC software allows for off-line analysis

Weighing in at 7.8kg (17.3lbs), including the batteries, the Maxwell system is highly portable; and with a typical battery life of 8 hours is an ideal inspection partner in the field.

PECT can normally be applied to ferromagnetic steel with wall thickness (WT) between 3mm (0.15”) - 50mm (2.0”).

A maximum surface temperature of up to 550°C (1020 °F) may be inspected with the PECT technique, provided the PECT probe is kept below 80°C (175 °F).

Maximum Lift-Off range is 0 – 250mm (0-10”).
