Choosing a 80 mm General Purpose Pressure Gauge

80 mm general purpose pressure gauges provide dry mechanical indication for routine duties in stable conditions. 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 point, then confirm the units, connection size, thread form and entry position. The stated accuracy for this dial size is ±2.5% FS.

Check the specified copper-alloy wetted parts against the medium. If vibration causes pointer flutter, compare a filled gauge.

Selecting a 80 mm Gauge

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

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 ±2.5% FS. Consider what that full-scale allowance means at the pressures you need to read.

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 relates to the full measuring span; check its value in pressure units for the chosen range.

General Purpose Construction

Check the specified copper-alloy wetted parts against the medium. If vibration causes pointer flutter, compare a filled gauge.

Applications

Suitable for local indication, replacement and equipment applications where the 80 mm format and general purpose construction suit the duty.

Existing gauge positions

Replace an 80 mm indicator after checking the mounting and connection.

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 80 mm fit

Do not assume an 80 mm case shares the fixing dimensions of another size.

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 80 mm gauges?

The stated accuracy is ±2.5% of full scale. Check the selected product for its complete specification.

Why choose a 80 mm dial?

An 80 mm dial can suit an existing installation without moving to a 100 mm case.

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.
