I hope this list includes the term you need:
- crasher system
- crash measuring device
- crash pressure gauge
- impact measuring system
- impact gauge
- shock wave measuring device
...(and other combinations)...

Had you provided the whole sentence or even the entire paragraph it would've been much more helpful.
This way I can't tell if it is about compressed air, hydrodynamics, weather, weapons, shipbuilding, earthquakes or something else.
