40mm Bottom Entry Industrial Pressure Gauge


40mm Bottom Entry Industrial Pressure Gauge

The 40mm Bottom Entry Industrial 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 an industrial pressure gauge is required at the point of measurement.

The bottom entry connection suits upright installation on pipework, manifolds, gauge valves and equipment ports, with the dial presented towards the operator for local reading. The industrial construction provides a robust mechanical pressure indicator for plant, machinery and packaged equipment where local indication is preferred over electronic display hardware.

This gauge is suited to engineers, OEMs and maintenance teams specifying a direct-reading pressure instrument for routine monitoring, commissioning and equipment checks. 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 bottom entry connection suits the pipework, manifold or equipment port orientation.
  • Check the gauge construction, range and connection against the site specification before installation.
  • Select a pressure range that allows normal operating pressure to sit comfortably within the scale.

Applications

Compact OEM Equipment

40mm size and bottom entry connection make this gauge practical for machinery builders requiring local pressure indication in restricted spaces.

Pneumatic Control Panels

Brass wetted parts are well suited to compatible pneumatic media, with the small dial fitting neatly into compact control assemblies.

Pump and Skid Assemblies

Bottom entry mounting allows straightforward installation on pipework, small manifolds and packaged process skids.

Maintenance Replacement Gauges

The 304 stainless steel case and compact format make it a practical replacement option for general industrial pressure indication duties.

Features

Dial

The 40mm dial suits compact equipment and local indication points where panel space is limited. It provides a practical analogue pressure reference for routine checks.

Configuration

The bottom entry connection is intended for mounting from below the gauge, commonly used on pipework, regulators and equipment manifolds.

Construction

A 304 stainless steel case provides external corrosion resistance, while brass wetted parts suit compatible pressure media in general industrial service.

Accuracy

The stated accuracy is 2.5%, supporting dependable local indication where a compact industrial pressure gauge is required.
