Sealed Case Subsea Pressure Gauges

The Ashford Instrumentation range of sealed case subsea pressure gauges feature an extremely robust  sealed case which is machined from a solid stainless steel block and is capable of withstanding the external pressure of the seawater outside the case. Atmospheric pressure of 1 bar is trapped within the case and is used as the reference pressure against which the process pressure is measured. This style of gauge should be used when the pressure of the process media needs to be measured against atmospheric pressure at sea level.
