100mm Back Entry General Purpose Pressure Gauge
100mm Back Entry General Purpose Pressure Gauge
The 100mm Back Entry General Purpose Pressure Gauge from GNW Instrumentation provides local pressure indication for industrial equipment, pipework, machinery and maintenance replacement duties. Its clear 100mm dial gives operators and engineers a practical reading point where a general purpose 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 general purpose construction is intended for compatible liquids and gases in standard industrial environments, offering an economical mechanical gauge option for routine monitoring and replacement work.
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 100mm dial where a balance of readability and compact size is required.
- Confirm the back entry connection suits the panel, fascia or equipment-front mounting arrangement.
- Use for standard compatible services where a general purpose mechanical gauge is appropriate.
- Select a pressure range that allows normal operating pressure to sit comfortably within the scale.
