Compact Industrial Pressure Indication for Local Mounting

The 40mm Bottom Entry Glycerine Filled Pressure Gauge from GNW Instrumentation provides local pressure indication in a compact format for industrial equipment, panels and machine assemblies. Its 40mm dial is appropriate where available space is limited, while still giving operators and maintenance teams a clear pressure reference close to the process connection.

As a glycerine filled pressure gauge, it is particularly relevant where vibration or pressure pulsation may affect pointer stability. The liquid filling helps damp movement, supporting easier visual reading in service conditions commonly found on machinery, hydraulic equipment, lubrication systems and compressed air installations. Selection should always take account of the process medium, connection arrangement and required indication tolerance.

The bottom entry layout supports upright installation into compatible ports, manifolds and pipework, making the gauge straightforward to position for routine checking. A 304 stainless steel case provides a durable external housing for industrial environments, while brass wetted parts should be matched with suitable media before specification. The stated accuracy of 2.5% is intended for local indication duties where a compact mechanical gauge is required rather than high-precision measurement.

Specification Considerations

When specifying this industrial pressure gauge, consider the installation position, available clearance and compatibility with the service conditions. The compact 40mm size is often chosen by OEMs and maintenance teams where a larger gauge would be impractical, but a direct visual indication is still required at the point of use.
