A PRESSURE TRANSDUCER FOR THE MEASUREMENT OF PRESSURES CAUSED BY UNDERWATER EXPLOSIONS

摘要

A pressure transducer, for measurement of pressures caused by under water explosions comprising a sensing element which has a pile of two quartz crystal discs connected in parallel with interleaving copper foil electrodes, the central electrode forming the positive electrode, the remaining two electrodes connected to each to form the negative electrode and two metal pistons on opposite side of said pile being located within a gauge body secured to a gauge holder.
