Wilcoxon underwater accelerometers are designed to be used virtually anywhere under continuous submersion. They are built to withstand the high pressures of deep submergence. Titanium cases are used when the accelerometer must be highly resistant to galvanic corrosion or mounted on titanium structures. Stainless steel can be used for applications where the accelerometer will be mounted on cast iron or mild steel structures since they are near one another on the galvanic series list.
