Abstract
Shorted guard‐ring quartz gauges 1.27 cm diam and 0.32 cm thick with a 0.36 cm inner electrode exhibit an effective piezoelectric current coefficient of k = (1.89 + 0.0107σ)×10−8 C/cm2/kilobar within a precision of ±1%, when subjected to step impact loading between 20 and 26 kilobar. Data confirm that the effective charge‐collecting area of the inner electrode includes half the area of the insulating gap. Increase of current with time is observed to be approximately three times that observed for shunted gauges. Unequal potential between inner and outer electrodes has no measurable influence on gauge response for the applications considered here. A comparison of present data with previous studies indicates that shorted guard‐ring quartz gauges do not display the same degree of universality as shunted quartz gauges.Keywords
