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.

nresolved asset integrity problem in the industry. Current methods for measuring wall thickness with liftoff, without removing insulation, all have severe limitations. Eddyfi introduces Lyft — a reinvented, high-performance pulsed eddy current (PEC) solution. The patent- pending system features a state-of-the-art portable instrument, real- time C-scan imaging, fast data acquisition with grid-mapping and dynamic scanning modes, and flexibility with long cables. It can also scan through thick metal and insulation, as well as aluminum, stainless steel, and galvanized steel weather jackets. Who else but Eddyfi to reinvent an eddy current technique and redefine CUI programs. Got Lyft?
