Overview

The Dakota CMX1-DL represents the professional standard in ultrasonic material testing, specifically engineered to tackle the challenges of corrosion and erosion monitoring. As an authorized representative, Seven Star LLC offers the Dakota CMX1-DL (Part Number: Z-171-0005) to engineering teams who require the ability to measure the thickness of the base metal without removing protective coatings or paint. The Dakota CMX1-DL is housed in a rugged, gasket-sealed aluminum enclosure, ensuring it can withstand the extreme conditions found in offshore, petrochemical, and power generation facilities.

What sets the Dakota CMX1-DL apart is its dual-mode capability, allowing operators to switch between standard Pulse-Echo and Echo-Echo (Thru-Paint) modes seamlessly. The “DL” designation signifies the inclusion of a high-capacity internal data logger, enabling the Dakota CMX1-DL to store 1,000 individual readings with sequential tagging. This makes the Dakota CMX1-DL an indispensable tool for long-term mechanical integrity programs where data accuracy and traceability are paramount.

Measurement Principle

The Dakota CMX1-DL utilizes advanced ultrasonic wave technology to determine material thickness. In standard Pulse-Echo mode, the Dakota CMX1-DL measures the time it takes for a pulse to travel from the transducer to the back wall and return. For coated surfaces, the Dakota CMX1-DL employs the Echo-Echo (Thru-Paint) principle. In this mode, the Dakota CMX1-DL measures the time between two consecutive back-wall echoes, effectively subtracting the thickness of the coating from the measurement.

This advanced processing within the Dakota CMX1-DL ensures that only the actual metal thickness is displayed, eliminating the need for time-consuming coating removal. The Dakota CMX1-DL also features an automatic gain control (AGC) and manual gain adjustment, allowing the user to fine-tune the signal for highly attenuative materials or complex geometries. This makes the Dakota CMX1-DL highly effective on pitted and irregular surfaces.

Engineering Design and Construction

The Dakota CMX1-DL (Z-171-0005) is engineered for field survival. Its case is precision-machined from extruded aluminum, providing superior EMI shielding and impact resistance. The Dakota CMX1-DL features a custom-designed, high-contrast LCD with a 60Hz refresh rate, ensuring that thickness readings are updated in real-time without lag. The integrated backlight allows the Dakota CMX1-DL to be used in confined spaces or dark industrial environments.

The Dakota CMX1-DL is equipped with dual Lemo 00 connectors, ensuring a robust and noise-free electrical path to the transducer. The keypad of the Dakota CMX1-DL is a sealed membrane type, offering excellent tactile feedback while preventing the ingress of liquids or dust. Power management is optimized in the Dakota CMX1-DL, providing up to 200 hours of continuous field use with only two standard AA batteries.

Frequently Asked Questions

What is the main advantage of the Dakota CMX1-DL Echo-Echo mode?

The Echo-Echo mode in the Dakota CMX1-DL allows the operator to measure the true thickness of the metal without having to remove paint or coatings from the surface. This saves significant time during inspections and maintains the corrosion protection of the asset.

How does the Dakota CMX1-DL handle data management for large projects?

The Dakota CMX1-DL features an internal data logger that can store up to 1,000 thickness measurements. These readings are stored sequentially and can be transferred to a computer for detailed analysis and reporting using the included Dakota NDT software.

Is the Dakota CMX1-DL (Z-171-0005) rugged enough for offshore use?

Absolutely. The Dakota CMX1-DL is designed with an extruded aluminum housing and gasket-sealed membrane, making it highly resistant to the salt, moisture, and impacts typically encountered in offshore oil and gas environments.

Can the Dakota CMX1-DL be used with different types of transducers?

Yes, the Dakota CMX1-DL is compatible with a wide range of Dakota NDT dual-element transducers (1MHz to 10MHz). The gauge features auto-probe recognition to ensure the electronics are perfectly matched to the sensor frequency.

Does the Dakota CMX1-DL provide velocity calibration for unknown materials?

The Dakota CMX1-DL allows for both single-point and two-point calibration. If the thickness of the material is known, the Dakota CMX1-DL can calculate the acoustic velocity of that specific material for precise measurement.
