European representation of PRAGMA NDT

12/09/2013

Imaginos NDE has introduced the PRAGMA NDT range of ultrasonic phased array equipment to the European NDT market.

The PRAGMA technology has been designed and developed by a highly-experienced NDT team under the watchful eye of François Mainguy, who NDT professionals may recognise from Harfang, the company that François previously founded and owned.

PRAGMA specialises in the design, manufacturing and retail of portable instruments and systems for NDT. PRAGMA’s products are meant for market sectors such as aerospace, petrochemical, transport and heavy industries. The goal is to provide the NDT market with portable instruments and systems that perform to a high standard, yet are simple to use and application-driven.

PRAGMA NDT has come to market with a selection of high-specification ultrasonic phased array equipment, including the PRAGMALite platform, PAUT 16/128 and ORTHOMATIC 60 scanner.

The PRAGMA NDT PAUT 16/128 is a 16-channel phased array NDT beam-former for portable applications, multiplexing over 128 elements, 100 MHz sampling per channel, 16-bit A-scan, plus many other advanced features.

The square-wave pulsers are running at 180 V peak-to-peak and feature a special circuitry to maximise the transfer of piezoelectric energy. Each beam signal (A-scan) can be calibrated with static focusing (SPAF), dynamic focusing on reception (DFR), distance-amplitude correction (DAC), time-corrected gain (TCG) and angle-corrected gain (ACG).

The pulsing and data acquisition can be running at a fixed PRF or triggered by position with 1 or 2 quadrature encoders.

The PAUT 16/128 unit can also be used with the PRAGMALite platform, which offers the user a modular NDT instrument platform for portable applications. It is said to be ideal for inspection companies, consultants and training schools.

PRAGMALite allows the user to easily switch between different NDT methods on the same instrument, including:

UT – standard flaw detection and C-scanning.
TOFD – B-scan imaging with encoder for improved sizing accuracy.
PAUT – linear and sector scan imaging for improved speed and POD.
EMAT – pulse-echo, guided waves and high-temperature, without the need for couplant.
ECT – surface inspection with multi-frequency and multi-channel solutions for tube, pencil and rotary probes.
