Displacement
Many displacement and positioning transducers are commercially available that are suitable for use with e-corder. Depending on their specifications.

They may connect directly to an e-corder input, or require a bridge amplifier or other signal conditioner.
The Chart recording software can differentiate a position signal with respect to time thus giving measure of velocity. Alternatively the output from a velocity sensor can be integrated to give a position signal.
Listings of many types of displacement and velocity sensors can be found at:
Large amplitude motions can be monitored with string potentiometers. See:
Very small displacements can be measured with fiber optic systems:
