Hallo,
We need piezoelectronic pressure sensor for oscilloscope measurement up to 120 bar or less (40 bar) for observe dynamic pressure waves during pulsed arc electro hydraulic discharge (3 kv) between iron rods into distilled water environment .
The main demand for pressure sensor is that it should work in the water environment under voltage (as during discharges contact fluid is in touch with sensor) and it also should catch 300 nanosecond duration pressure waves. Any design is secondary meaning.
Mainly sensors have metal body (with thread) which I think would be affected voltage damage or measurement failure.
Could you propose any product suitable for our measurement OR may consult with different measurement solution of dynamic pressure change (for example, indirect measurement of pressure change by sound waves, etc.)
Also need temperature sensors for water temperature change during discharge. It sholudn’t be as fast response as pressure sensor.
see reference:

Thank you for supporting in advance and waiting for your positive reply. Regards, Vladimer Mikelashvili
Thank you. Although i couldn't find PDF version of this article. in researchgate such name of your link exist but when downloading, other article appeared. I found other article of this author : Normal Reflection Characteristics of One-Dimensional Unsteady Flow Shock Waves on Rigid Walls from Pulse Discharge in Water , Dong Yan, Jinchang Zhao, and Shaoqing Niu. There is CY-214 pressure sensors but they are used with charge amplifier, transient recorder, and computer.
I think there exist sensors which can directly connected with oscilloscope.
