Dakota NDT HD Thru-Coating Thickness Probes

Dakota NDT HD Thru-Coating Thickness Probes

High Damped Thickness Gauging Probes for both Pulse Echo & Echo-Echo Measurements

HD - High Damped Probes have better multiple-echoes for Thru-Coating measurements. HD probes are required for Echo-Echo Thru-Coating Measurements with ZX-6/ZX-6DL, MMX-7 & MVX and can be used in Pulse Echo (P.E.) mode with all Dakota Corrosion Gauges and in Echo-Echo (E.E mode) on the above listed gauges as well as the CT series. 

Echo-Echo Mode

For Thru-Coating Thickness Gauging

  • For Dakota's Thru-Coating gauges using Echo-Echo mode, such as the ZX-6, MMX-6 and MVX, HD (High Damped) probes are needed.
  • The 5MHz ¼” UT-DU-T-102-2700 is used most frequently
  • The 5 MHz 3/16” UT-DU-T-101-2700 is used on small diameter tubes
  • The 7.5 MHZ, 3/16” High Damped UT-DU-T-101-3000 is suggested if high resolution is needed to measure thinner material and find smaller pits
  • The 3.5 MHz ½” UT-DU-T-104-9700 is suggested for thicker materials

Size Options (Dual Element)

3/16" Version


1/4" Version


1/2" Version

Note: Custom sizes are available upon request. Old style stainless steel ring assemblies that do not extend flush to the face of the transducer are also available for custom builds upon request.

Connector Options (Dual Element)


Potted (Integral)


Microdot


Lemo 00

Note: The Potted and Microdot versions can be either "Top" or "Side" entry configurations. The Lemo connectors are only available in 1/2" transducer configuration, due to space requirements. 

3.5 MHz Dual Element Transducers

3.5 MHz x 1/2" dual element transducers are recommended for measuring through thick coatings on tanks, pipes and vessels.

5.0 MHz Dual Element Transducers

5 MHz is the most commonly used thickness gauging frequency. Go to a lower frequency for greater penetration and less noise on grainy materials and step up frequency for higher resolution and thinner materials.
