High-temperature transducers

Dear colleagues

I would like to know if there are any commercial ultrasonic transducers able to perform measurements up to 1500 °C

I saw that both Panametrics and Krautkramer catalogs show transducers that work up to 500 °C

Re: High-temperature transducers
Hey
What couplant are You going to used at 1500 °C?
I have done many measures at about 600°C and at that temperature You only get a few seconds to measure before the couplant get´s burn.

Re: High-temperature transducers
That's the interesting thing....the material to test is a liquid...no need to couplant ;)

Just joking of course....I learned that there is no transducer for these temperatures. However maybe one could place a ceramic wedge in front of the probe. It could be an interesting attempt.

Extended Range Variable Wall® Piping Calibration Blocks for Longseam Inspection

This set of two blocks has been specially designed for situations where ultrasonic examination tak
...
es place circumferentially or “around the curve” for applications such as inspection of longseam welds in piping and vessels. Jointly designed by PH Tool and Holloway NDT, the blocks feature side-drilled hole reflectors positioned within novel compound-curves, each with multiple thickness steps. The unique design results in a light and compact form factor, with the largest block weighing just over 15 lbs and spanning just 16 ¾”. Coverage is provided for nominal pipe sizes from 6” to 10” in the small block and 12” to a whopping 56” in the large block. The compound OD curves and multiple wall thicknesses actually exceed ASME requirements, providing exceptional signal response and measurement accuracy. Properly managing beam divergence off the ID and stabilizing beam skew due to probe rocking is essential to maintaining a consistent calibration when inspecting lengthwise on curved surfaces.
