Pulse-Echo (P-E) and Echo-Echo (E-E) Modes

                ZX-6 in Pulse-Echo (P-E) Mode               A-Scan showing P-E measurement

 
Pulse-Echo Mode (P-E)

Pulse-Echo (P-E) Mode measures from the surface to the back-wall echo. It is used on bare material to determine wall loss on corroded, eroded and pitted materials. When measuring through a coating the measurement will include an error due to the coating thickness x 2-3 because of the difference in sound velocity between the coating and test material.

Echo-Echo (E-E) Mode

Echo-Echo (E-E) Mode measures from the back-wall echo to its multiple-echo and eliminates the error due to the coating. Measurements can only be made on materials that have parallel surfaces as the multiple-echo will disappear if the back-wall is corroded or pitted.

 

Part 2:

CMX High Performance Material & Coating Thickness Gauges with advanced Thru-Coating Capability

Dakota CMX instruments have both basic modes - Pulse-Echo (P-E, 0-1st echo) and Echo-Echo (E-E, Thru-Coating), as well as PECT mode and other additional modes depending on the specific gauge. More details about these additional modes can be seen below.

CMX Series Measurement Modes


      CMX-DL+ PECT Mode                 CMX-DL+ A-Scan PECT           CMX Digital Display

Pulse-Echo-Coating (PECT) Mode - Coating On

Measures Thru-Coating, detects pitting and measures when Echo-Echo (E-E) mode fails. PECT is a unique method that provides the benefits of Pulse-Echo (P-E) and Echo-Echo (E-). Measure coated material without errors caused by the coating while being able to measure on materials with corroded and pitted back-walls.

Echo-Echo-Verify (E-EV) Mode

The Echo-Echo-Verify (E-EV) mode measures between 3 reflections. Similar to Echo-Echo (E-E) mode, this technique is commonly used to eliminate errors from surfaces with multiple-layers of coatings. The primary benefit of this mode is that it compares the 2nd and 3rd echoes to verify that a peak jump has not occurred in order to provide an additional level of confidence in the measurement.

Pulse-Echo Temperature Compensated (PETP) Mode - Temp Comp

Temperature changes in the probes delay lines as result of increasing/ decreasing measurements. This mode creates a constant zero and eliminates the need for frequent Probe Zeroing.

CMX CT Mode

 
Coating-Only (CT) Mode

Coating-Only (CT) Mode is a custom hybrid combination mode using special techniques to effectively measure the thickness of coatings.

Features

A-Scan (Rectified Display) showing a lamination

A-Scan Display

A-Scan shows the signal that is being measured.

B-Scan showing various irregular thicknesses

B-Scan Display

View More Details

B-Scan graphs a series of measurements. This results in a profile view that is helpful to understand if the material has a single or series of pits, general corrosion, inclusion or lamination.

Digital Display

The CMX Series' digital display is simple, direct reading, and can add min/max.
