Abstract

In Fig 1, hat A is shown with probe B and computer controller C. Probe B is instrumented with a seven cantilever-beam transducer using the differential strain gage method. The tip of probe B has seven actuating rods which cause the cantilever beams to bend when the probe tip contacts a piston cluster on hat A.

Computer Controlled Piston String Forces Measurement System

      In Fig 1, hat A is shown with probe B and computer controller
C. Probe B is instrumented with a seven cantilever-beam transducer
using the differential strain gage method.  The tip of probe B has
seven actuating rods which cause the cantilever beams to bend when
the probe tip contacts a piston cluster on hat A.

      Balancing resistors and any additional electronics are held
inside probe B housing, ane electronic signals from the strain gages
in probe B are sampled by computer C through cable D.  The seven
strain gage outputs corresponding to the seven pistons at each piston
site are graphically displayed on the computer screen as a realtime
bar chart and piston diagram.  Software allows users to archive
piston force measurements for each piston site for future data
analysis and/or Statistical Process Control.
