The auto find feature locates the detection point(s) and adjusts the display settings to bring the waveform into view.

The high speed scan feature on the PG70ABDL precision thickness gauge speeds up the inspection process by taking 32 measurements per second. Remove the transducer from the test material and display the minimum measurement scanned.

PG70ABDL Features Explained

Repeatability / Stability Indicator
Consisting of 6 vertical bars, when all the bars are fully illuminated and the last digit on the digital thickness value is stable, the gauge is reliably measuring the material thickness.

High Speed Scan with Minimum Thickness Display
By significantly increasing the measurement refresh rate this mode allows the user to make scanned passes over the test material. The smallest thickness value is held in memory and displayed when scanning is complete. This feature can also be used in conjunction with the minimum & maximum limit alarm feature (model dependant).

Differential Mode
Once a user defined nominal thickness value has been set, the gauge will display the +/- thickness difference from the nominal value entered.

Limit Alarm Mode
The user can define minimum and maximum thickness limits. If the measurement falls outside the upper or lower limit a red LED will light and the beeper sounds. A green LED will light to indicate an acceptable thickness.

V-Path Correction

Dual element transducers consist of a probe with two crystals (one to transmit and one to receive the sound pulse). The crystals are separated by an acoustic barrier - generating a 'V-shaped' sound path as the sound travels from one element to the other. 
This path is slightly longer than the direct path therefore V-path correction is used to calculate the correct thickness.

PG70ABDL Measurement Modes Explained

Pulse - Echo Mode (PE): The normal display mode, measures the total thickness from the base of the transducer probe to the material density boundary (typically the back wall). Ideal for pit and flaw detection.
Echo - Echo Mode (EE): Also known as the ThruPaint? Mode, EE ignores the coating thickness, displaying the material thickness from the top surface of the material to the material density boundary.
Interface - Echo Mode (IE): More accurate than the PE mode, IE displays the total thickness from the top surface to the material density boundary - i.e. ignores the couplant thickness.
