This type of gauge has a solid wall between the dial and the gauge mechanism.  The idea behind this design is that in the event of over-pressurization and failure of the Bourdon Tube, process fluid would be directed out the back of the gauge, reducing potential harm to operators.  (the back of the case is designed to give-out under a certain amount of pressure).
Safety gauges are common in the chemical processing industry, since many of the fluids used in that industry are harmful to operators if they escape the system.

In some cases customers want their name and logo on the dial and in others the dial may be calibrated to read in GPM (Gallons Per Minute).  Some of our customers prefer the use of color or symbols on their dial rather than numbers.  For instance, when the pointer moves from the "green zone" to the "red zone", it may signify a problem.

Pressure gauges can be customized in other ways too.  The inlet can be at any orientation to the dial and there are several different case styles to choose from, including flange, panel and front mounted cases.  Some gauges even glow or light-up for dark areas.
