Pundit 250 Array - Ultrasonic Imaging Scanner
The Pundit 250 Array is the latest development in Ultrasonic Pulse Echo equipment from Proceq. This unit combines an 8 channel shear wave transducer array with the industry leading Pundit Touchscreen controller, the probe can also be upgraded to 16 channel by combining two transducer arrays.
The Pundit 250 Array is available as a unit with touchscreen controller or as an upgrade to any Pundit PL unit.
Applications
- Thickness measurement of elements up to approximately 1m
- Location of defect such as honeycombing, voiding and the depth and extent of concrete delamination.
- Detection of embedments such as pipes, tendon ducts beneath a layer of rebar
- Location of objects and defects in fibre reinforced concrete
Features
- Durable ceramic contact points on dry contact transducers
- Superior near field performance [Detection of objects and embedments close to test subject's surface]
- Upgradeable to a 16 channel array with 2 probe units
- Single or double handle configurations
- System control buttons on handles and probe for quick single operator use
- Raw data export
- Real Time B Scan updates
- Extended B scan panoramas
- Automatic estimation of the Pulse Velocity or calibration to a known thickness
Ultrasonic Pulse Echo Method
The Pulse Echo technology widely extends the application range of the Pundit Touchscreen Unit and offers a variety of special features.
Scan Modes
Real Time B-Scan
Panorama B-Scan
Transducer Specifications
The Pundit Array transducer is a rugged and lightweight 8 channel array of shear wave transducers.
One channel will transmit a sonic pulse the remaining 7 receive, this measurement is repeated for each channel transmitting in turn.
The 56 A-Scan signals are mapped using Synthetic Aperture into a B-Scan Image like the examples above, showing information on changes in material such as the back surface of a slab, embedments or defects internal to it.
Other Compatible Pundit Sensors
The Pundit touchscreen is also compatible with the Single Channel UPE transducer and Proceq's range of Ultrasonic Pulse Velocity transducers, the links below discuss the relevant systems:
