80mm Pressure Gauges

100mm pressure gauges provide clear local pressure indication for plant, pipework, skids and process equipment where a larger dial is preferred. The 100mm face helps operators read pressure more easily during routine checks, commissioning and maintenance.

This range supports industrial pressure measurement and pressure monitoring needs across replacement gauges, OEM equipment and industrial systems. Before ordering, check the required pressure range, process connection, mounting style, case materials and media compatibility against the individual product specification.

100mm Gauge Selection

100mm Pressure Gauges are used where a larger dial face is helpful for clear local pressure indication on plant, pipework, skids and process equipment. The increased dial size can improve readability compared with smaller compact gauges, particularly where operators need to view pressure from a short distance.

This collection supports industrial pressure measurement requirements across maintenance, replacement and new equipment applications. Options may include dry gauges for routine service and glycerine-filled gauges where vibration or pressure pulsation needs to be reduced, depending on the individual product specification.

When replacing an existing pressure gauge, match the pressure range, process connection, mounting style, case size and media compatibility before ordering. Engineers and procurement teams should also check the product details for material construction and any application-specific requirements.

Clear Dial Visibility

The 100mm dial size provides easy-to-read local pressure indication for plant rooms, production areas and process equipment.

Dry or Filled Options

Select dry gauges for general monitoring or glycerine-filled versions where damping is required for vibration or pulsating pressure.

Industrial Replacement Use

Suitable for maintenance stock, equipment refurbishment and like-for-like replacement where the gauge specification matches the existing installation.

Typical Applications

These larger dial pressure indicators are commonly used in industrial systems where reliable visual pressure readings are required during operation, inspection or maintenance.

Process Pipework

Used for local pressure indication on pipework, manifolds and process lines where operators need a readable gauge at the point of use.

Pump Systems

Applied to pump discharge or suction monitoring where pressure readings assist with routine checks, fault finding and system balancing.

Industrial Skids

Installed on packaged equipment, OEM skids and control panels to provide a visible mechanical pressure reference.

Maintenance Replacement

Specified for replacing worn, damaged or unreadable gauges when the pressure range, connection and mounting arrangement are compatible.

Choosing the Right Gauge

Before selecting a 100mm pressure indicator, confirm the operating conditions and compare them with the individual product specification.

Pressure Range

Choose a gauge range that suits the normal operating pressure and any expected pressure peaks. Avoid selecting solely by dial size.

Connection and Mounting

Check the process connection type, connection position and mounting style against the existing installation or equipment drawing.

Dry or Glycerine Filled

Dry gauges are used for routine pressure measurement, while filled gauges can help stabilise the pointer in vibrating or pulsating applications.

Media and Environment

Review the listed wetted materials, case construction and environmental suitability to ensure compatibility with the process media and location.

100mm Pressure Gauge FAQs

Common buyer questions about selecting, replacing and installing 100mm dial pressure gauges for industrial use.

When should I choose a 100mm pressure gauge?

Choose a 100mm gauge when clearer dial visibility is required, especially on plant, process equipment or installations where readings are taken from a short distance.

Can I replace a smaller gauge with a 100mm gauge?

Only if the pressure range, connection, mounting position, available space and application suitability are compatible. Check the product specification before replacing.

What is the difference between dry and glycerine-filled gauges?

Dry gauges are suitable for general monitoring. Glycerine-filled gauges provide damping, which can improve readability where vibration or pressure pulsation is present.

What details do I need before ordering a replacement gauge?

Confirm the pressure range, dial size, connection type, connection position, mounting arrangement, media compatibility and whether a dry or filled gauge is required.
