40mm Back Entry Glycerine Filled Pressure Gauge

40mm Back Entry Glycerine Filled Pressure Gauge

The 40mm Back Entry Glycerine Filled Pressure Gauge from GNW Instrumentation provides local pressure indication for industrial equipment, pipework, machinery and maintenance replacement duties. Its compact 40mm dial gives operators and engineers a practical reading point where a glycerine filled pressure gauge is required at the point of measurement.

The back entry connection is intended for panel, fascia, enclosure or equipment-front mounting, allowing the dial to remain visible while the pressure connection is made from behind. The glycerine filling helps damp pointer movement caused by vibration or pressure pulsation, supporting a steadier local indication in demanding service conditions.

This gauge is suited to engineers, OEMs and maintenance teams specifying a direct-reading pressure instrument for routine monitoring, commissioning and equipment checks. The wetted material compatibility should be checked carefully, particularly where brass wetted parts are used. Final selection should consider the required pressure range, process medium, vibration level, operating temperature and installation layout.

Selection and Installation Considerations

Before ordering, compare the gauge configuration with the existing installation or project specification. Correct selection helps improve readability, service life and measurement confidence.

• Use the 40mm dial where installation space is restricted and close-range reading is acceptable.
• Confirm the back entry connection suits the panel, fascia or equipment-front mounting arrangement.
• Check media compatibility with the wetted parts and use the filled case where vibration damping is beneficial.
• Select a pressure range that allows normal operating pressure to sit comfortably within the scale.
