Scanners - PortaScan
NDT Systems manufacture several standard scanners for the PortaScan system. Shown here are 2 of the most common scanners.
Above is our P4-12, Pipe Scanner. It incorporates a set of powerful magnetic wheels to hold itself on a pipe of 4" diameter to flat, as well as drive itself around the pipe. The cross carriage shuttle is mounted on 4 stainless steel recirculating ball bearings. The screw drive is a zero backlash design to minimize any mechanical hysteresis. The transducer sits in the spring loaded shuttle below to assure consistent contact with the material under test. There are "In & Out" BNC connectors in the head of the scanner. This relieves any excess weight of a cable from pulling on the transducer itself, again assuring consistent coupling.
An optional cantelever arm mounts to the scanner and is driven by the shuttle through the narrow end of the scanner to approach surfaces where clearance is a problem.
Automated PipeScanner
VS1M X-Y Series Scanner
The new VS1M X-Y Scanner incorporates a unique rack & pinion, 'V' rail design and is driven by 2 high torque stepper motors. In this view the scanner is fitted with 3 manually operated suction cup feet (the third is hidden under the unit in the rear). This arrangement is ideal for relatively flat and smooth surfaces. Just pump the cups down and the scanner is held in almost any inclination. These feet are interchangeable with flat plate mounts or direct mount to a surface for more of a permanent test station.
The transducer is mounted on a removable, spring loaded, dual ball bearing, dual gimbol arrangement thereby allowing it to follow moderate contour changes while keeping the transducer in constant contact with the surface.
This scanner also incorporates our "In & Out" BNC connectors on the head of the scanner. This relieves any excess weight of a cable from pulling on the transducer itself, again assuring consistent coupling.
