The Dakota NDT UMX-2 Underwater Thickness Gauge is a highly specialized and robust ultrasonic thickness gauge engineered for professional subsea applications. It's designed to provide accurate and reliable material thickness measurements in challenging underwater environments, with an impressive depth rating of 1000 ft (approximately 305 meters). This makes it an indispensable tool for divers, remotely operated vehicle (ROV) operators, and marine inspection teams performing integrity assessments on pipelines, offshore structures, ship hulls, and other submerged assets.
The UMX-2 is noted for its flexibility in transducer options, supporting optional dual or single membrane probes. This versatility allows it to adapt to various inspection needs and material conditions. It features auto probe recognition and zeroing, simplifying setup and ensuring consistent measurements.
A key strength of the UMX-2 lies in its multiple measuring modes, providing comprehensive analysis for diverse applications:
Dual Element Probes (for corrosion/pitting):
P-E (Pulse-Echo): Standard mode for overall thickness, capable of detecting pits and flaws.
E-E (Echo-Echo): "Thru-paint" mode, allowing measurements of remaining metal thickness through coatings up to 0.16 inches (4 mm) without requiring coating removal.
PECT (Plural Echo Coupling Recognition): A more advanced mode that provides independent readings for coating thickness, base material thickness, and can still detect pits and flaws.
Single Element Probes (for precision/thin materials):
Triple Echo (TCG - Time Corrected Gain): This mode provides high precision and is particularly useful for measuring very thin materials or surfaces with complex geometries.
The gauge is pre-programmed with eight preset material types, simplifying setup for common metals like steel, aluminum, and cast iron. Additionally, it includes one custom programmable material type, allowing users to input specific sound velocities for unique materials. A five-position gain switch offers manual control over signal amplification, which is crucial for optimizing readings on different materials or surface conditions.
The UMX-2 includes an extensive Data Logger capable of storing 5,000 readings and waveform captures. This feature is vital for comprehensive record-keeping, trend analysis, and post-inspection reporting. The ability to capture waveforms (A-Scan) provides visual verification of the ultrasonic signal, enhancing confidence in the readings and aiding in troubleshooting complex measurements.
The instrument is housed in a robust, waterproof enclosure designed to withstand the harsh subsea environment. It is typically powered by rechargeable batteries, providing sufficient operational time for extended dives.
