Process for assembly of multimode hydrophone ceramic stack

A method of assembling a hydrophone is provided in which the method stacks ceramic rings, delrin washers, and LC-800 washers such that a top edge of a composite stack extends beyond a top of a hydrophone flange. By measuring the voltage on each ceramic ring while an end cap and a socket head cap scr...

Zusammenfassung:	A method of assembling a hydrophone is provided in which the method stacks ceramic rings, delrin washers, and LC-800 washers such that a top edge of a composite stack extends beyond a top of a hydrophone flange. By measuring the voltage on each ceramic ring while an end cap and a socket head cap screw are installed; the axial compression of each ceramic ring is quantified; thereby, providing an opportunity to equalize the axial compression of each ceramic ring to yield an accurately performing hydrophone.
