100mm Bottom Entry Industrial Pressure Gauge for Local Pressure Indication

The 100mm Bottom Entry Industrial Pressure Gauge from GNW Instrumentation provides clear local pressure indication for industrial pipework, equipment panels, packaged plant and maintenance points. Its 100mm dial size gives operators and engineers a practical viewing area for routine checks, commissioning work and fault finding where a direct mechanical reading is preferred.

The bottom entry format is well matched to installations where the gauge is mounted vertically from a gauge valve, manifold or pipe take-off, with the dial presented forward for normal viewing. This configuration is commonly specified where pipework approaches the instrument from below, helping to keep the installation simple and easy to inspect during service.

With a 304 stainless steel case and brass wetted parts, this industrial pressure gauge is intended for compatible non-corrosive media in general industrial environments. The stainless steel case supports day-to-day durability in plant areas, while brass wetted components provide a practical choice for many standard pressure measurement duties. The stated accuracy is 1%, which should be checked against the required measurement tolerance, process conditions and any site-specific instrumentation standards.

Selection and Installation Considerations

When specifying a pressure gauge for industrial service, the connection orientation, dial readability and material compatibility are often as important as the pressure range itself. This 100mm bottom entry model is a practical option where engineers require a robust local indicator without adding unnecessary complexity to the installation.

• Choose the bottom entry layout where the instrument is mounted from pipework or a valve beneath the gauge.
• Confirm that brass wetted parts are compatible with the process medium before installation.
• Check that 1% accuracy is appropriate for the monitoring duty and operating conditions.
• Position the gauge so the 100mm dial can be read safely during routine inspection.
