PosiTector UTG- Ultrasonic Wall Thickness Gauge

UTGPipe ADV 3.86mm CMYKKnowing the thickness of metal or plastic from one side is very important.  The PosiTector UTG metal thickness tester from DeFelsko can be used for a number of applications such as:

  • Checking the specification of materials that have been delivered 
  • or Measuring the remaining wall thickness due to corrosion a gauge

This compact ultrasonic tester has all of the features required for site work with all the technology you expect from a premium product.

Theory

PosiTector UTG probes transmit an ultrasonic pulse into the material to be measured. This pulse travels through the material towards the other side. When it encounters an interface such as air (back wall) or another material, the pulse is reflected back to the probe. The time required for the pulse to propagate through the material is measured by the Gage, represented as t1 and t2 right.

Single-EchoPosiTector UTG C and UTG M (in single-echo mode) probes determine thickness by measuring t1 (uncoated) or t2 (coated), dividing it by two and then multiplying by the velocity of sound for that material (steel).

For uncoated materials t1 relates directly to material thickness. When a material is coated the propagation time is increased and is shown above as t2.

Coatings such as paint have a slower velocity of sound than that of metal. Thus the single-echo technique will produce a thickness result greater than the actual combined coating+metal thickness.

The PosiTector UTG M in multiple-echo mode determines thickness by measuring the time between at least three consecutive back wall echoes.

Multiple-EchoIn the figure right, multiple-echo mode measures only the time between echoes. Regardless of whether the steel is coated or not, all times between echoes are the same. In multiple-echo mode, the Gauge determines thickness by measuring t1+t2+t3, dividing it by six and then multiplying by the velocity of sound for that material. The resultant thickness calculation made by the instrument is therefore an accurate measurement of the steel thickness only, disregarding the coating thickness.

Select from 2 Probe Styles

UTG C – Corrosion Probe

PosiTectorUTG-CMeasures the wall thickness of materials such as steel, plastic and more. Ideal for measuring the effects of corrosion or erosion on tanks, pipes, or any structure where access is limited to one side.

  • 5 MHz dual element transducer with durable PEEK probe tip
  • Automatic V-Path compensation for thin materials

UTG M – Multiple-Echo Probe

PosiTectorUTG-MFeatures Thru-Paint capability to quickly and accurately measure the metal thickness of a painted structure without having to remove the coating. The most accurate method to measure the remaining wall thickness of a painted structure because it automatically disregards the coating, lowering inspection time and expense. Also ideal for measuring on sandblasted materials or other applications requiring a durable wear face.

  • 5 MHz contact probe with wear resistant Alumina probe tip
  • Multiple Echo technique averages 3 or more echoes for accurate and reliable readings
  • Toggle easily between
    • Multiple Echo mode to eliminate coating thickness and…
    • Single Echo mode to detect pits and flaws, and to increase the measurement range
