force sensor...

[John Honnold]

Daniel:

    Most dynamometers have a strain gauge built in.  How else could you
measure torque on a water break dyno.?  Most strain gauges have very
good temperature stability and the fit between the engine and the
stand.  When the engine pivots, it pulls( or pushes ) on the strain
gauge.  Measuring across the strain gauage and supplying this value to
one side of a bridge will give you pretty torque measurement.

Regards,

John Honnold
