Dakota - Model CMX -Corrosion Thickness Gauges
Top of the range and easy to use, the Dakota CMX Corrosion Thickness Gauges provide inspectors with all the features necessary to measure the material and coating thickness at the same time.
Intelligent
User definable limits for pass/fail indication
Set limits for pass/fail indication on individual reading or for each batch with audible & visual warnings.
Powerful
Store each measurement for further analysis
Up to 4GB of readings can be saved into the gauge memory as each measurement is taken, which can be downloaded later into an inspection application or into DakMaster™ Software for further analysis and reporting.
Versatile
Able to measure coating and material thickness
The Dakota CMX Ultrasonic Thickness Gauges have the ability to measure coatings and material thickness simultaneously while maintaining the ability to locate pits, flaws and defects in the material.
Customisable
Choose & customise the reading display
The Dakota CMX Thickness Gauge range has a choice of display modes allowing the user to select the most appropriate for their needs; Readings, B-Scan, B-Scan combined with readings, Scan bar & the A-Scan on the Dakota CMX2-DL Corrosion Thickness Gauge and Dakota CMX3-DL Corrosion Thickness Gauge.

Dakota CMX 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
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.
Similar to the PE mode, PETP takes into account and compensates for the variations in measurement caused by temperature variations.
The echo-echo verify mode measures by comparing the values between 3 reflections and is commonly used to eliminate errors from surface coatings and to make measurements in multiple layered materials.
Displays the thickness of the coating applied to the material.
Displays both the material thickness (PE) and the coating thickness (CT) at the same time.
Basic Flaw Mode (FLAW MODE):
Basic prove-up flaw detection using single element angle beam transducers is available on the CMX2-DL and CMX3-DL corrosion thickness gauges.
Material Thickness Digits Display:
The standard display on all models, this displays the numerical thickness value in either millimetres (MM)or inches (IN).
Scan Bar Display:
A linear graphic display which allows users to graphically monitor changes in thickness readings. As the scale range can be adjusted by the user, this display is ideal for observing tiny variations in material thicknesses.
B-Scan Display:
A time based cross sectional 2D block view of the thickness provides a graphical view of the material thickness - ideal for relative depth analysis.
A-Scan Display; Full Wave (RF):*
The A-Scan display shows the sine wave created by the reflected sound, or oscillation, from the material being measured. In RF mode the full wave form is displayed.
A-Scan Display; Rectified (+ or -):*
Users can select to view either the positive or the negative cycle of the full waveform (RF). This rectified (RECT) display shows the amplitude of the echo versus the transit time.
* Available on CMX2-DL and CMX3-DL thickness gauge Models only
