I believe Bruce's product would be improved a good deal if the sensors were removed from the board and instead were potted into, say, a billet aluminium housing that was directly bolted to the side of the cabinet. Leads would then connect to the board/box. Added advantage would be that if a sensor went down it could be unplugged and replaced.

Also with long tubes you get resonance effects which also adds an uncertaincy value to the readings.
You would then pickup all the vibrations in the sensor that your bench would be getting from everywhere else?

In the design of the PTS DM thought was given to all of this and it was decided "noise" was not a bad thing and was taken into account with the averaging algorithm that is being used in the software.

Something to think about
