Measurement examples

The following figures show examples of measurements with the FOPH 2000:

Shockwave

 
Pressure signal in the focus of an electromagnetic shock wave generator.

Negative pressure

 
High negative pressure generated by sound-soft reflection (inversion) and focusing of a positive pressure wave.

Pressure pulse of a cavitation bubble

 
Short time pressure pulse emitted by a single stable oscillating cavitation bubble, measured in 0.6 mm distance to the bubble (2000 averages).

Temperature pulse

 
Temperature pulse in water generated by an underwater heating wire, measured in 1 mm distance to the wire.
