Compact Back Entry Pressure Indication

The 40mm Back Entry Glycerine Filled Pressure Gauge from GNW Instrumentation provides compact local pressure indication for machinery, panels and industrial assemblies where space is limited. Its 40mm dial format is practical for close-mounted readings, particularly where a full-size gauge would be difficult to accommodate.

As an industrial pressure gauge glycerine filled, this model is intended for installations where vibration or pressure pulsation may affect pointer stability. The glycerine fill helps support a steadier indication during routine monitoring, making it a practical choice for hydraulic equipment, OEM machinery and packaged plant where operators need clear front-facing pressure visibility.

The back entry arrangement allows the gauge to be mounted from the rear into a panel, enclosure or machine face, helping maintain a clean installation layout. A 304 stainless steel case provides external durability in industrial environments, while brass wetted parts should be checked for compatibility with the pressure medium before specification.

Specification Considerations

This 40mm gauge is specified with 2.5% accuracy, which is appropriate for general local indication and maintenance checks where precision process measurement is not required. When selecting a replacement or specifying for new equipment, confirm the connection style, installation space, media compatibility and required accuracy against the application.

• 40mm dial for compact local pressure indication
• Back entry layout for panel, enclosure or machine mounting
• Glycerine filled construction for improved readability under vibration
• 304 stainless steel case with brass wetted parts for compatible media
