Looking for a hydraulically damped pulley

Looking for a hydraulically damped pulley

Looking for a hydraulically damped pulley

I have to repeatedly drop a 1Kg load through 2m at about .3m/s.  At first a hydraulic rate controller looked attractive until I found that they tend to be used for much greater forces and get very expensive at longer travels.  An apps guy suggested I look for some sort of damped pulley.  One could call it a dynamometer.  Any ideas?

RE: Looking for a hydraulically damped pulley

There are rotational dampers available that you can set to give a desired speed given a certain load. Look at www.dictator.de and look for hydraulic dampers, radial dampers.

Other companies also have them, look around.

For a small weight like this a magnetic damper should work, too. You could even use it with an encoder or tachometer
