The load capacity of a new differential pressure gage that has been de
veloped has been increased 24-fold by precompression of the piezoelect
ric elements. The system proposed for force transmission in the gage s
ignificantly increases the conversion factor. The gage is also more th
ermally stable than previous designs. The symmetry and monolithic cons
truction of the force-transmitting system enhances the vibrational sta
bility of the gage and alleviates hysteresis.
