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.

Choosing a 80 mm Pressure Gauge

80 mm pressure gauges provide local indication for machinery, plant and process equipment. This intermediate size offers more viewing area than a 63 mm gauge without requiring the space of a 100 mm case.

Choose the range around the normal operating pressure, then confirm the scale units, connection size, thread form and bottom- or back-entry arrangement. Mechanical gauges in this size are specified at ±2.5% FS; check the individual product for its complete specification.

Compare general-purpose, glycerine-filled, industrial and all stainless steel gauges according to the operating conditions and required materials.

80 mm Gauge Selection

80 mm describes the nominal dial diameter, not the pressure range or connection. This intermediate size offers more viewing area than a 63 mm gauge without requiring the space of a 100 mm case.

When replacing an instrument, record the full scale, units, thread form, connection size and entry position. Matching the dial diameter alone is not enough.

Mechanical gauges in this size are specified at ±2.5% FS. Because this is based on full scale, consider the resulting allowance at the readings you need to monitor.

80 mm Dial

This intermediate size offers more viewing area than a 63 mm gauge without requiring the space of a 100 mm case.

±2.5% FS Accuracy

The accuracy allowance is based on the complete measuring span rather than the current reading.

Typical Applications

Suitable for local pressure indication, maintenance replacement and equipment builds where a 80 mm dial and the selected specification suit the duty.

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.

How to Choose

Select the pressure range, choose the required construction, match the connection and confirm that the dial will fit and remain readable.

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.
