40mm Bottom Entry Glycerine Filled Pressure Gauge


40mm Bottom Entry Glycerine Filled Pressure Gauge

The 40mm Bottom 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 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 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 bottom entry connection suits the pipework, manifold or equipment port orientation.
  • 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.

Applications

Compact OEM Machinery

40mm bottom entry format fits neatly into restricted machine spaces where operators need local pressure indication on compatible services.

Hydraulic and Lubrication Systems

Glycerine filling helps steady the pointer on vibrating hydraulic power packs and lubrication circuits using media compatible with brass.

Compressed Air Panels

On pneumatic panels, the compact stainless steel cased gauge provides local indication without taking up excessive space.

Manifolds and Test Rigs

Bottom entry mounting works well on small manifolds and test rigs where vertical gauge orientation and close-to-port reading are required.

Features

Dial

The 40mm dial gives a compact reading point where panel or machine space is limited. Its small format is suited to local pressure indication close to the process.

Configuration

The bottom entry connection supports vertical mounting into pipework, manifolds or equipment ports. This configuration helps keep the gauge upright for straightforward local reading.

Construction

A 304 stainless steel case provides a robust external housing for industrial environments, while brass wetted parts suit compatible media. Check process compatibility before specifying.

Accuracy

The stated accuracy value of 2.5% helps buyers assess whether the gauge meets the required local indication tolerance. Match this figure against the application’s measurement requirement before selection.
