50mm Industrial Pressure Gauges

The 50 mm industrial pressure gauges cover compact equipment where 40 mm is too small and larger gauges will not fit. Select construction according to the duty rather than choosing by diameter alone.

Choosing 50mm Industrial Pressure Gauges

The 50 mm industrial pressure gauges cover compact equipment where 40 mm is too small and larger gauges will not fit. Select construction according to the duty rather than choosing by diameter alone.

The collection contains a dry back-entry gauge alongside glycerine-filled alternatives. Stated accuracy is 2.5%. Confirm filling, mounting and the wetted materials rather than assuming every version is identical.

The intermediate size helps with replacement work, but thread form and connection position still need checking. Where pressure pulsation causes unstable readings, consider the glycerine-filled option.

Selecting a 50 mm Gauge

The intermediate size helps with replacement work, but thread form and connection position still need checking. 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.

2.5% Accuracy

The stated accuracy is 2.5%. 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 50 mm format and industrial construction suit the duty.

Equipment assemblies

Fit a pressure indicator into an existing machine layout.

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 contains a dry back-entry gauge alongside glycerine-filled alternatives. Stated accuracy is 2.5%. Confirm filling, mounting and the wetted materials rather than assuming every version is identical.

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 50 mm fit

Compare case depth and connection position when replacing an older gauge.

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 50 mm gauges?

The listed models are specified at 2.5% accuracy. Confirm the allowable error for the selected span and operating conditions.

Why choose a 50 mm dial?

The 50 mm format balances a modest case size with local readability.

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.
