Precision A-Scan Thickness Gauge

Precision A-Scan Thickness Gauge

Highlights:

▶ Adjustable square wave pulser provides the flexibility necessary for

both high resolution and penetration requirements.

▶ Selectable viewing options provide the user with additional flex-

ibility during operation: (RF waveform, +/- Rectified waveform, and

Large Digits with Scan Bar.

▶

Time based B-Scan feature displays a cross section of the test

material. Displays the prole of the opposite surface of the mate-

rial.

▶

Ability to use a variety of single element transducers for spe-

cic applications: Standard Delay Line (acrylic and graphite tips

for metals and thin plastics), Pencil Delay Line (tough access

areas on thin materials), and Contact transducers (variety of

applications).

▶

Hardware AGC gain control for multiple echo and thru-

paint measurement.

▶

Multiple calibration options: One-Point, Two-Point,

or selection from a Material List.

▶

16 factory setups and 48 user-defined setups.

ser-defined setups can be edited for custom applica-

tions.

▶

PVX is equipped with an alpha-numeric data

logger to provide increased versatility for those

custom reporting needs.

▶

The High Speed Scan feature speeds up the

inspection process by taking 32 measurements

per second. Remove transducer from the test

material and display the minimum measure-

ment scanned.

▶

Adjustable resolution settings add to the

PVX’s exibilty.

▶

PVX comes complete with our Windows®

PC software for transferring data to and from

a PC.

▶

Auto Find feature locates the detection

point(s) and adjusts the display settings to

bring the waveform into view.

▶

Visual and audible alarm with Hi and Lo

limit settings for specific application tolerances.

▶ Multiple language support.

▶ 2 year limited warranty.
