This accelerometer may be treated as a charge source. Its sensitivity is expressed in terms of charge per unit acceleration (pC/ms–2, pC/g). The DeltaShear design consists of three piezoelectric elements
and three seismic masses arranged in a triangular configuration around a triangular centre post. They are held in place by a clamping ring that isolates the configuration from the base. The ring also prestresses the piezoelectric elements to give a high degree of linearity.
This design provides a high sensitivity-tomass ratio, a relatively high resonance frequency and high isolation from base strains and temperature transients. The piezoelectric element used in Type 4391 is a PZ 23 lead zirconate titanate element, and the housing material is titanium.
