Dakota FX71-DL Ultrasonic Flaw Detector
Overview
The Dakota FX71-DL Ultrasonic Flaw Detector is a versatile handheld NDT instrument developed for ultrasonic flaw detection, defect sizing, and weld inspection in industrial environments. It is designed for inspectors and maintenance engineers who require a portable yet powerful solution for detecting internal discontinuities such as cracks, voids, inclusions, and lack of fusion in metallic components. In addition to flaw detection, the FX71-DL also supports ultrasonic thickness measurement, making it suitable for combined inspection tasks.
The FX71-DL features a rugged portable design suitable for field use in oil and gas facilities, fabrication workshops, power plants, and heavy industrial sites. Its high-resolution color display provides clear waveform visualization, allowing inspectors to accurately interpret ultrasonic signals during inspections. The instrument is engineered for reliable operation in demanding environments where accuracy, repeatability, and inspection efficiency are critical.
Ultrasonic Technology & Inspection Modes
The Dakota FX71-DL utilizes advanced ultrasonic pulse-echo technology for flaw detection and material evaluation. It supports A-Scan display for real-time signal analysis and B-Scan imaging for visual representation of internal structures and defect location. The instrument includes industry-standard evaluation modes such as DAC and TCG, enabling accurate defect sizing and compliance with common inspection procedures and codes.
The FX71-DL allows flexible adjustment of key ultrasonic parameters, including gain, pulse width, and velocity, enabling optimization for different materials, probe types, and inspection scenarios. This flexibility makes it suitable for both routine inspections and more advanced NDT applications.
Data Logging & Inspection Workflow
The FX71-DL includes built-in data logging functionality, allowing inspectors to store ultrasonic waveforms, thickness readings, and inspection results directly within the instrument. Stored data can be reviewed on the device or transferred to external software for reporting and documentation purposes. This supports structured inspection workflows where traceability and inspection records are required for quality assurance and asset integrity programs.
Industrial Applications
The Dakota FX71-DL Ultrasonic Flaw Detector is commonly used for weld inspection, crack detection, and flaw evaluation in structural steel, pipelines, pressure vessels, and fabricated components. Typical industries include oil and gas, power generation, petrochemical processing, manufacturing, and maintenance services. Its portability and multifunction capability make it suitable for field inspections, shutdown maintenance, and workshop quality control.
Installation & Use Notes
Accurate flaw detection requires appropriate ultrasonic probes and proper coupling between the transducer and the test surface. Surface condition and probe selection have a significant impact on signal quality and defect detection sensitivity. The FX71-DL is compatible with standard ultrasonic transducers used for flaw detection and thickness measurement. Basic surface preparation improves inspection reliability, and inspection parameters should be configured according to applicable NDT procedures and standards.
