The Design of a Piezo-Electric Gauge for Closed Vessel No. 21
Abstract
This report is the third and final one of a series describing Closed Vessel apparatus in use in the A.R.E., the other two dealing respectively with Closed Vessel design (Ref. I.) and the development of the recording apparatus (Ref. 3). Since it was first introduced for routine purposes in the present connection, the design of Piezo-Electric gauge, employing tourmaline as the pressure-sensitive element, has closely followed that developed by the Gun Experimental Section for the recording of pressure-time phenomena in guns. A brief account of modifications, mainly in the method of attaching the crystal to its electrodes, which have been made in recent years is followed by a description of the present gauge design and the manner in which it is calibrated. Further developments are envisaged in the method of gauge assembly, and anticipated changes in calibration technique, to enable the Closed Vessel dP/dt pressure recorder to be employed in the determination of gauge sensitivity, are briefly outlined.
