Frequently Asked Questions

What is this pressure gauge used for?

It provides local indication of system pressure for monitoring, setup and maintenance.

How do I choose the correct pressure range?

Select a range that covers normal and maximum operating pressure without routinely running the pointer at the end of the scale.

What is the difference between dry and liquid-filled gauges?

Liquid-filled gauges can help damp vibration and pulsation, while dry gauges are simpler and common in steady applications.

Why does mounting style matter?

Connection location and panel-mount hardware determine how the gauge fits the equipment or instrument panel.

When is stainless construction useful?

Stainless cases or wetted parts are useful in corrosive, washdown or demanding industrial environments, depending on the exact model.

How do I choose dial size?

Larger dials improve readability at a distance, while smaller dials suit compact equipment.

Can any gauge be used with any media?

No. Wetted-part materials and seals must be compatible with the media.

When should a gauge be replaced?

Replace it if it is damaged, leaking, no longer returns correctly to zero or shows unreliable readings.
