Dakota NDT CMX1 & CMX1-DL (Formerly CMX & CMXDL)

Dakota NDT CMX1 & CMX1-DL (Formerly CMX & CMXDL)

The CMX1 measures thickness, detects internal pitting on coated pipes and tanks, while also measuring the coating thickness simply and cheaply!

Measures Material & Coating Thickness Simultaneously

The CMX1 has all the features of the ZX gauges with a ton of advanced features. Measure material and coating thickness simultaneously, while still detecting pits & flaws in a single mode (PECT). Auto probe zero, auto probe recognition, auto temperature compensation are also included. Selectable Large Digits and B-Scan display options, up to 64 custom user definable setups, selectable transducer table for precision linearity, and material and coating calibration options are also available.

Our standard thru paint mode is is still included and ongoing. Switch between modes, according the transducer recognized or manually selected. 5 position 12dB gain switch allows the user to adjust to certain material types and be successful with common but difficult application scenarios. A built-in TDG (time dependent gain) feature is incorporated into our transducer list for use with attenuative materials. It's all very nicely packaged in a small portable aluminum extrusion for extra durability. USB-C connectivity, 4gb internal SD memory with file system. Screen capture to .tif. Our DakMaster java-based PC or MAC OSX software is also part of the kit.

 

 

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.
