Dakota NDT CMX2-DL & CMX3-DL (CMXDL+ & CMXDL+C)

Dakota NDT CMX2-DL & CMX3-DL (CMXDL+ & CMXDL+C)

Multi-Mode Thickness Gauge in one easy-to-use, economical instrument.

A/B Scan Material & Coating Thickness Gauges

The CMX2-DL & CMX3-DL gauges have all the features of the basic CMX1 models, plus a full featured A-Scan presentation with RF and Rectified viewing options. The CMX2-DL is equipped with 3 fully independent gates (start, stop, width, & Threshold). Equipped with a 110dB gain range for added flexibility with a variety of transducer types and applications. Selectable 50 volt pulser boost or cut (100 – 200 volts). The CMX3-DL color version offers a rotating portrait or landscape option to increase the A-Scan viewing area. Our DakMaster java-based PC or MAC OSX software makes this kit truly the Cadillac of the CMX series.

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.

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.
