Figure I.7 shows a adapter/transducer combination that measures travel
at the chain sprocket in the mechanism cabinet. A hex adapter (3/8" - 24
to 8mm) is mounted on the TR3170 rotary transducer and is attached to
the rotating element in the cabinet. The transducer hex adapter is
attached to the rotating mechanism and then to the support plate. The
support plate is the clamped to the structural plate in the cabinet using
C-clamps.

Figure I.8 shows an adapter for use with the HVB SF6 Gas circuit
breakers that uses a ganged operating mechanism. The adapter has a
metric 16mm thread that treads into a tapped hole on the horizontal
operator adjacent to pole 1 and the mechanism cabinet. This is shown
with a 24" travel rod.
