Choosing a 100 mm Glycerine-Filled Pressure Gauge

100 mm glycerine-filled pressure gauges provide damped indication where vibration or pulsation affects a dry pointer. 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.

The filling steadies pointer movement but does not increase the pressure rating. Confirm the wetted materials and temperature limits.

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.

100 mm Dial

Its larger dial is easy to check from a normal working distance on plant, pipework and equipment panels.

±1.6% FS Accuracy

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

Glycerine-Filled Construction

The filling steadies pointer movement but does not increase the pressure rating. Confirm the wetted materials and temperature limits.

Applications

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

Plant inspection points

Read pressure during routine rounds or maintenance checks.

Pumps and compressors

Use filled indication where operating vibration affects readability.

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

Confirm the wetted materials and temperature limits for the process fluid or gas.

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 filling protect against every pressure surge?

No. The selected range and overload capability must still suit the system; additional protection may be needed.

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.
