Digiquartz® Transducers and Depth Sensors offer high resolution and high accuracy absolute depth measurements to 7000 meters. They are the key sensors used in tsunami warning systems, wave and tide gauges, inverted echo sounders, towed arrays, underwater mapping systems, subsea vehicles, and construction and oil platform leveling. The Absolute Pressure Gauges are used in the dual-purpose Seismic + Oceanic Sensors (SOS) for Ocean Disasters and Geodesy modules.
