Thus the single-echo technique will produce a thickness result greater than the actual combined coating+metal thickness. PosiTector 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).įor uncoated materials t1 relates directly to material thickness. When a material is coated the propagation time is increased and is shown above as t2.Ĭoatings such as paint have a slower velocity of sound than that of metal. The time required for the pulse to propagate through the material is measured by the Gage, represented as t1 and t2 right. When it encounters an interface such as air (back wall) or another material, the pulse is reflected back to the probe. This pulse travels through the material towards the other side. PosiTector UTG probes transmit an ultrasonic pulse into the material to be measured. This compact ultrasonic thickness gauge has all of the features required for site work with all the technology you expect from a premium product. Measuring the remaining wall thickness due to corrosion.Measurement of in situ materials, through coatings if required.Checking the specification of materials that have been delivered.The PosiTector UTG metal thickness tester from DeFelsko is an Ultrasonic Thickness Gauge which can be used for a number of applications such as: Knowing the thickness of metal or plastic from one side is very important.
