Measuring Impact Velocity with a Ballistic Pendulum Prototype

[knosaj]

some device or contraption to measure point impact velocity - ballistic pendulum ?

i hope you guys and gals can point me in the right direction for a prototype i am working on.

I am looking for a device that measures impact velocity. much like a ballistic pendulum only much sturdier than the ones I've seen online. it has to be able to take a lot of abuse

it doesn't need to be a complete item, i can work with anything that i will be able to rig together, mount on a pole and take the measurement.

it should operate with a pendulum type motion. it doesn't have to be small, but it should be portable.

thank you in advance for your help.

anyone?

maybe something that is already in production that i can retro fit?

i have seen the hydrology velocity meters, but i am not sure this would measure the same type of velocity that i am looking for. besides the one i have seen may not stand up to the impacts i will subject it to.

thanks again.
