There is described a system comprising mechanical equipment and an apparatus for monitoring and/or controlling the mechanical equipment. The mechanical equipment vibrates at a frequency f.sub.vibration in use, and the apparatus is attached to the mechanical equipment such that the apparatus also vibrates when the mechanical equipment is in use.
