About the 50 mm Range

The 50 mm general-purpose gauges provide a compact mechanical pressure indication for machine maintenance and building-services equipment. They offer a little more dial space than the 40 mm versions without requiring a larger instrument housing.

Select a bottom-entry gauge for an upright connection or a back-entry model where the process connection is behind the dial. These are dry gauges with brass wetted components for compatible media and relatively stable pressure conditions. The stated accuracy is ±2.5% FS.

When replacing a 50 mm gauge, confirm the existing thread before ordering. Instruments that look identical from the front may use different thread forms, even if they share the same dial size.

Selecting a 50 mm Gauge

When replacing a 50 mm gauge, confirm the existing thread before ordering. Instruments that look identical from the front may use different thread forms, even if they share the same dial size.

50 mm Dial

50 mm dial for installations where a compact gauge must still be easy to read close up.

±2.5% FS Accuracy

±2.5% FS stated accuracy, subject to the chosen range and operating conditions.

General Purpose Construction

Bottom- and back-entry versions for different mounting arrangements.

Applications

Suitable for local indication, replacement and equipment applications where the 50 mm format and general purpose construction suit the duty.

Equipment assemblies

Fit a pressure indicator into an existing machine layout.

Service systems

Monitor routine pressure on equipment with a suitable medium and range.

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

Check the specified copper-alloy wetted components against the process medium.

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 available 50 mm general-purpose gauges are specified at ±2.5% of full scale. The exact error allowance depends on the scale range.

Why choose a 50 mm dial?

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

When should I choose another construction?

Consider a filled gauge for vibration or a different wetted material where the medium requires it.

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.
