The Dakota MX Corrosion Thickness Gauge range have large, easy to read displays and provides users with A and B-Scan options for accurate interpretation of measurements.

The Dakota MX corrosion thickness gauge is available in two models: MX1-DL Thickness Gauge and MX2-DL Thickness Gauge. Both models offer 2D cross sectional block view, providing a graphical representation of a material’s thickness, ideal for accurate analysis and identification of pits and corroded areas.

MX1-DL Ultrasonic Thickness Gauge: Taking 250 readings per second in scan mode, the internal data logger stores up to 4GB worth of data together with their waveforms.

MX2-DL Ultrasonic Thickness Gauge: As well as all the features of the MX1-DL Thickness Gauge, the MX2-DL Thickness Gauge also features an A-Scan display, allowing users to fully interpret and control measurement readings. The user can select to view either the full waveform (RF) or the rectified waveform (RECT) showing either the positive or the negative cycle of the full waveform.

• Measures uncoated & coated surfaces – Flexible & easy to use, the Dakota MX Corrosion Thickness range doesn’t just measure uncoated surfaces but can also measure coated surfaces. Using Echo Echo ThruPaint™ Mode (EE), coatings up to 1mm are ignored.
• Store up to 4GB of readings and waveforms or B-Scans – Taking 250 readings per second in scan mode, the internal data logger stores up to 4GB of readings together with their waveforms.
• Choose & customise the reading display – The Dakota MX ultrasonic 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 MX2-DL Corrosion Thickness Gauge
• 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.
