Choosing 100mm Industrial Pressure Gauges

The 100 mm industrial pressure gauges cover plant installations where readings must be checked clearly during inspections. Select construction according to the duty rather than choosing by diameter alone.

The collection offers the dry and filled mounting combinations actually listed. The current models share 1% stated accuracy. Check the process-contact materials and connection.

The larger dial gives more space for scale divisions, provided the case and connection suit the mounting point. Where pressure pulsation causes unstable readings, consider the glycerine-filled option.

Selecting a 100 mm Gauge

The larger dial gives more space for scale divisions, provided the case and connection suit the mounting point. Where pressure pulsation causes unstable readings, consider the glycerine-filled option.

Duty-Specific Construction

Confirm whether the selected model is dry or liquid-filled, and check its wetted materials.

1% Accuracy

The stated accuracy is 1%. Compare the allowable error at the selected full scale with your measurement requirement.

Installation Check

Confirm the process connection, mounting position and expected pressure conditions.

Applications

Suitable for local indication, replacement and equipment applications where the 100 mm format and industrial construction suit the duty.

Plant inspection points

Read pressure during routine rounds or maintenance checks.

Plant maintenance

Match a replacement gauge to the existing range and installation.

Replacement instruments

Check the scale, entry position and connection against the original gauge.

Equipment checks

Use the specified accuracy to decide whether the gauge suits the readings being checked.

How to Choose

The collection offers the dry and filled mounting combinations actually listed. The current models share 1% stated accuracy. Check the process-contact materials and connection.

Confirm the range

Cover normal operation and expected peaks while keeping the required readings easy to interpret.

Check the medium

A 316 stainless-steel case provides the external construction. Check wetted-part materials separately for process compatibility.

Check the 100 mm fit

Check the viewing angle and space around the larger case.

Match the connection

Check the exact thread and the entry position offered by the selected product.

Frequently asked questions

Practical answers to help with selection and replacement.

What is the accuracy of these 100 mm gauges?

The listed models are specified at 1% accuracy. Confirm the allowable error for the selected span and operating conditions.

Why choose a 100 mm dial?

A 100 mm dial gives more viewing area for routine readings and checks.

Does the stainless-steel case determine media compatibility?

No. Check the wetted components and seals, which contact the process medium.

Will it fit an existing gauge connection?

Check the thread form and size, entry position and case dimensions. Matching the dial diameter alone is not enough.
