  • Page 7: Chapter One Introduction

    CHAPTER ONE INTRODUCTION The Dakota NDT model FX70 is both, an ultrasonic flaw detector, as well as an ultrasonic A/B Scan thickness scope, in a single unit. It’s a combination of both our CMX3-DL, as well as our new FX70 flaw detector series. Why is this advantageous? Thickness gauge are specifically setup to very accurately measure thickness, locate pits, flaws and blind surface corrosion.

This method uses a combined empirical and mathematical model to eliminate the need for a large range of reference standards, generally required when using the DAC or TCG methods.

    FX70 Series Ultrasonic Flaw Detector Considerations:  Should only be used with single element probes.  The effective diameter must be estimated for standard transducers not certified for DGS.  Center frequency clarity is required.
