40mm Back Entry Industrial Pressure Gauge


40mm Back Entry Industrial Pressure Gauge

The 40mm Back 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 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 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 back entry connection suits the panel, fascia or equipment-front mounting arrangement.
  • 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 Panels

40mm dial and back entry format suit small machinery panels where a front-facing industrial pressure gauge is required without side-mounted pipework.

Pneumatic Control Assemblies

Rear connection mounting works well on pneumatic control boxes and manifolds where brass wetted parts are compatible with the service media.

Pump and Compressor Skids

The stainless steel case offers a practical housing for skid-mounted pressure indication in plant rooms, service packages and compact process equipment.

Maintenance Replacement Gauges

This gauge is a useful replacement option where an existing 40mm back entry unit with brass wetted parts is specified.

Features

Dial

The 40mm dial provides a compact indication point where panel space or equipment footprint is limited.

Configuration

Bottom entryThe back entry connection supports rear-mounted installation, helping keep pipework and gauge faces neatly aligned on panels or equipment housings.

Construction

A 304 stainless steel case gives good external durability, while brass wetted parts should be matched to compatible process media.

Accuracy

The stated accuracy is 2.5%, so buyers should confirm it meets the tolerance required for the intended pressure measurement duty.
