Abstract
This invention relates to seismic transducer assemblies for converting compressional wave motion or acoustic energy into electric energy in a fluid medium such as is encountered in marshy terrains. It also relates to an improved method of manufacturing such transducers. The transducer includes a rigid hollow casing having a conical end cap to facilitate planting the casing into the ground. At least one pressure transducer element is mounted in the casing. A water-impervious, pressure-transmitting, insulating core fills the casing's cavity. The material rigidly holds the transducer in place and allows transfer of pressure energy from the fluid medium in which the transducer assembly is submerged, to the inner surfaces of the transducer element.
