Strong Engineering Foundation and Industry Reputation

Dakota NDT product philosophy focuses on building instruments that deliver stable, repeatable readings even under harsh field conditions such as offshore platforms, refineries, pipelines, high-humidity facilities and elevated-temperature environments. Their devices are engineered with advanced signal processing, precision transducer interfacing and robust housings that protect electronics from shock, dust, salt exposure and mechanical vibration.

Over the years, Dakota NDT has expanded its portfolio to meet the evolving needs of inspection teams, maintenance departments and quality control engineers. This includes continuous updates to measurement algorithms, improved digital interfaces, ergonomic housings and compatibility with a wide range of ultrasonic transducers for different inspection scenarios.

Ultrasonic Thickness Gauges for Corrosion Monitoring

One of Dakota NDT’s core innovations is its corrosion thickness gauge line, designed specifically for industrial environments where equipment degrades over time. These gauges help detect thinning in pipelines, pressure vessels, storage tanks, boilers, structural beams and other critical components. Corrosion models typically support:

• Echo-to-echo mode for measuring through paint and coatings
• High penetration capability for corroded or pitted surfaces
• Automatic gain control for consistent readings
• Field-calibration support for long-term accuracy

These instruments play a key role in maintenance planning, shutdown scheduling and risk-based inspection programs.

Precision Thickness Gauges for Quality Assurance

Dakota NDT also offers precision gauges designed for manufacturing, machining and engineering applications where very small thickness variations matter. Precision models provide:

• High-resolution measurement
• Fast response time
• Stability for thin metals, plastics, glass, ceramics and composites
• Compatibility with delay-line and immersion transducers

They are commonly used in aerospace, automotive, fabrication and production lines to ensure compliance with design tolerances.

Ultrasonic Flaw Detectors for Critical Inspection

Dakota NDT flaw detectors provide the functions needed for weld inspection, crack detection and comprehensive structural assessment. Typical features include:

• A-scan ultrasonic display
• DAC/TCG curves
• Adjustable gates for defect sizing
• Multi-mode flaw detection
• Support for a broad range of angle-beam transducers

These devices help inspectors identify subsurface defects, porosity, inclusions, weld discontinuities and structural weaknesses.

Bolt Tension Measurement Instruments

Bolt tension instruments from Dakota NDT use ultrasonic time-of-flight measurement to determine preload, elongation and stress in bolts and fasteners. They are widely used in:

• Turbines
• Compressors
• High-pressure flanges
• Structural steel connections
• Rotating equipment

Correct bolt tension is critical for preventing leaks, vibration issues and mechanical failure.

Full Range of Transducers and NDT Accessories

Dakota NDT manufactures a comprehensive suite of ultrasonic transducers, including:

• Dual-element probes
• High-temperature transducers
• Delay-line transducers
• Immersion probes
• Angle-beam probes

Along with couplants, cables and calibration blocks, these accessories ensure stable signal quality and reliable field performance.
