Choosing a 100 mm Industrial Pressure Gauge

100 mm industrial pressure gauges provide robust local indication for industrial machinery and plant. Its larger dial is easy to check from a normal working distance on plant, pipework and equipment panels.

Choose the range around the normal operating point, then confirm the units, connection size, thread form and entry position. The stated accuracy for this dial size is ±1.6% FS.

These models have stainless steel cases. Choose dry or filled construction for the operating conditions and check wetted parts separately.

Selecting a 100 mm Gauge

100 mm identifies the nominal dial diameter. Its larger dial is easy to check from a normal working distance on plant, pipework and equipment panels.

Select the measuring range independently of the case size. Then check the connection, entry position, wetted materials and operating conditions.

The stated accuracy for this dial size is ±1.6% FS. Consider what that full-scale allowance means at the pressures you need to read.

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

Confirm the range and accuracy, check the process medium, verify the available space and match the connection and entry position.

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 stated accuracy is ±1.6% of full scale. Check the selected product for its complete specification.

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.
