100mm Bottom Entry Low Pressure Capsule Gauge

The 100mm Bottom Entry Low Pressure Capsule Gauge from GNW Instrumentation is designed for low pressure indication where small pressure changes need to be shown clearly on a mechanical dial. Its clear 100mm dial makes it suitable for close-range reading on air, gas and low pressure systems where a standard pressure gauge may not offer the required sensitivity.

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. Capsule gauges are intended for low pressure measurement duties where sensitivity is more important than high pressure capability, so the pressure range should be selected carefully against the system conditions.

This low pressure gauge is best specified for suitable clean, compatible gases or low pressure services where operators need a local indication for balancing, proving or routine monitoring. The technical specification table should be checked for connection, accuracy and material details before ordering.

Low Pressure Gauge Selection Notes

Before ordering, compare the gauge configuration with the existing installation or project specification. Correct selection helps improve readability, service life and measurement confidence.

• Select a low pressure range that matches the expected operating pressure.
• Confirm the process medium is suitable for the gauge materials.
• Check the bottom entry layout and dial size against the available mounting space.
• Avoid overpressure conditions that could damage a sensitive capsule element.
