63 mm Severe Service Gauge

Brand: Marsh Bellofram Group of Companies

With available ranges to 10,000 psi, 63 mm Severe Service Gauges from Marsh Instruments are a series of liquid filled severe service gauges are expressly designed to provide reliable pressure measurements in harsh and demanding industrial and OEM environments, particularly where pulsation and vibration are a concern.

High pressure ranges offer a Helical Bourdon Tube for longer gauge life and increased durability.

The gauges are filled with glycerin to offer a dampening effect, while reducing pointer flutter, as well as offering significant shock reduction to instrument-grade components. They also lubricate internal components, effectively reducing risk of corrosion.

These all stainless steel liquid-filled gauges feature a ventable top fill plug for pressure relief and ease of venting after installation. They can be mounted on either a horizontal or vertical plane.

Units are hermetically sealed for reliable operation in harsh or dirty environments, while reducing the chance of leaks and ease of refilling in the field.
