The Dakota FX70 Flaw Detector is available in two models: Dakota FX70-DL Flaw Detector and Dakota FX71-DL Flaw Detector.

Whether you are on-site or in the laboratory these gauges are the tool you need for all your flaw detecting needs.

The time corrected gain (TCG) feature automatically compensates for sound attenuation through a material, further increasing the performance of the gauge.

The Dakota FX70 Ultrasonic Flaw Detector stores up to 4GB worth of readings with A/B-scan images in alpha numeric batches with full data logging and firmware updates via USB data output to DakMaster data management software.

Features:

• Exceptional visibility in sunlight (AMOLED)
• colour VGA display (320×240 pixels)
• Sizing Toolkits: DAC, AWS, TCG, DGS
• Pulse Repetition Frequency: 8 to 2000Hz, adjustable
• Detection: Z-Cross, Flank & Peak
• Automatic: probe zero, probe recognition, and temperature compensation
• Measurement: Variety of modes to address a number of applications
• Large data storage with multiple formats: Alpha numeric grid and sequential with auto identifier
• Download to DakMaster data management software

• Summary

  Versatile
  The Dakota FX70 Flaw Detector series has two functions, a thickness gauge and a flaw detector. When the Dakota FX70 Flaw Detector is set to thickness gauge it has the ability to measure coatings and material thickness simultaneously. When set to flaw detector the gauge has the ability to detect the size and position of flaws and to differentiate between flaw types in various materials and welded joints.
  	Intelligent
  	User definable limits for pass/fail indication. Set hi/lo limits for pass/fail indication with audible warnings and built-in differential mode for quality control inspections.
  Powerful
  Store each measurement for further analysis. Up to 4GB of readings can be saved into the gauge memory as each measurement is taken, which can be downloaded later into an inspection application or into DakMaster™ Software for further analysis and reporting.
  	Customisable
  	Customisable tool kits and reading display. The Dakota FX70 Ultrasonic Flaw Detector has a choice of display modes allowing the user to select the most appropriate for their needs; from A & B-Scan displays to flaw detection modes such as TRIG, DAC, TCG, Flank and Peak.

  Detection Methods

  Zero Crossing:	Flank:
  The gate detects the flank of the pulse, but the measurement is taken at the next crossing of the x axis. This is the most common type of detect in ultrasonic measurement.	The gate is triggered by the flank (or side) of the pulse on the graph and the measurement taken at this exact point.
  Peak:	TRIG:
  The gate is triggered by the intersection with the A-scan pulse and the detection is taken from the next peak in the signal (when it stops rising and starts falling).	TRIG enabling location of flaws in both surface distance and depth. Trigonometric display of beam path, depth, surface distance, and curved surface correction. Used with angle beam transducers.
  DAC:	AWS:
  Distance amplitude correction for the creation of DAC curves which are used to inform the operator of the size of any given flaw at any depth.	The American Weld Standard function provides automatic defect sizing in accordance with AWS D1.1 structural welding code.
  TCG:
  Time corrected gain increases gain as distance increases, in order to achieve an over all level of sensitivity for the same flaw/reflector at different distances.
