Compact Rear-Mounted Pressure Indication

The 40mm Back Entry Industrial Pressure Gauge from GNW Instrumentation provides a compact pressure indication point for equipment where space is limited and a front-facing dial is preferred. Its rear connection format helps support neat panel or housing installation, keeping the gauge face aligned with the operator while reducing exposed side pipework.

With a 40mm dial, this industrial pressure gauge is well matched to compact OEM assemblies, pneumatic control equipment, small skids and replacement duties where the existing installation calls for a back entry gauge of the same size. The stated accuracy is 2.5%, making it appropriate for general industrial indication where this tolerance meets the measurement requirement.

The 304 stainless steel case provides practical external protection for plant and equipment environments, while the brass wetted parts should be checked against the process medium before selection. This is particularly important for maintenance buyers replacing an existing gauge, where compatibility with the service fluid and connection arrangement must be confirmed.

Selection and Installation Considerations

Before ordering, engineers and procurement teams should confirm that the gauge format aligns with the mechanical layout, readability requirement and process compatibility of the installation.

• Check that a 40mm dial provides sufficient visibility for the operator position.
• Confirm the back entry connection suits the panel, enclosure or equipment housing.
• Verify that 2.5% accuracy is acceptable for the intended pressure indication duty.
• Ensure brass wetted parts are compatible with the process media.
