Subsea Compensated Diaphragm Pressure Gauges

March 2015


The Stewarts-USA range of compensated subsea pressure gauges have a 100% filled case that has a special compensation device,  allowing the internals of the case to be pressurized equal to the external ambient pressure as the gauge is submerged to depth. 


The benefit of this method is that as the internal and external pressure remain in balance, there is no need for a pressure proof case, allowing our 8000 series subsea compensated gauges to work at your deepest depth applications.

Specially developed to meet the need for gauges working at great depths under the sea and in hyperbaric conditions.  Measures the true pressure of the system with reference to sea level atmospheric pressure where the gauge case is sealed. Reinforced case prevents ambient pressure affecting the inlet pressure reading.
