Ultrasonic flaw detector reduces inspection times

The new Phasor XS from GE Inspection Technologies brings phased array flaw imaging capabilities to everyday inspection in an easy to use, portable and affordable ultrasonic flaw detector

The detector will drastically reduce inspection times and improve probability of detection.

It will find particular application in the power generation sector for weld inspection and corrosion mapping of vessels, pipework and structural steel sections.

With its familiar operating platform and easy to understand, menu driven inspection instructions, the new battery powered instrument requires little operator training and is available at less than half the price of conventional phased array systems, bringing phased array technology to routine manual inspection.

When used in phased array mode, the instrument offers up to 64 individual channels and the operator can electronically multiplex a multi element probe to achieve precise control over the angle of inspection, the amplitude and the depth of focus of each individual ultrasonic beam.

The inspection image is presented as a full colour, sector B-scan on the unit's high resolution TFT screen, providing comprehensive data in real time.

Any of the A-scans which make up the sector scan can be selected for separate display or for simultaneous display with the sector image to allow instant and reliable sizing.

Sector images and A-scans can be stored on a removable SD card for off line data analysis and management.

A wide range of array probes are compatible with the new flaw detector, including dialogue probes, containing probe identification data which can be transmitted back to the instrument to ensure increased inspection reliability, minimise set up errors and assist in probe operation calculations.

In conventional mode, the Phasor XS can use standard ultrasonic probes to carry out conventional inspection, including corrosion and thickness measurement.

Ruggedly packaged and weighing less than 4 kg, the Phasor XS offers an ideal entry level phased array solution to manual volumetric inspections in a wide range of power generation applications.

It can be carried up scaffolding and through difficult access points in the steam generator and turbine sections as well as throughout the balance of plant.

It is a logical progression of GE' s field-proven, flaw detection product range, complementing GE products such as the conventional USM 35 portable flaw detector and the sophisticated IAS 50 field deployable ultrasonic integrity assessment system which is designed for corrosion mapping and flaw detection and features automatic defect recognition (ADR).
