Marine Diaphragm Sealed Pressure Gauge

Introduction:

A marine diaphragm sealed pressure gauge is a type of pressure gauge specifically designed for marine applications. It is used to measure and display the pressure of liquids or gases in marine systems, such as those found on ships, offshore platforms, or other marine vessels.

The main characteristic of a diaphragm sealed pressure gauge is the presence of a flexible diaphragm that separates the process fluid (the medium being measured) from the internal components of the gauge. This diaphragm acts as a barrier, preventing the process fluid from coming into direct contact with the gauge's mechanical parts.

The diaphragm is typically made of a corrosion-resistant material such as stainless steel or other alloys suitable for marine environments. It can withstand the pressures and temperature ranges commonly encountered in marine applications.
