100 mm Severe Service Gauge
Brand: Marsh Bellofram Group of CompaniesWith available ranges to 10,000 psi, 100 mm Severe Service Gauges from Marsh Instruments are liquid-filled severe service gauges, expressly designed to provide reliable pressure measurements in harsh and demanding industrial and OEM environments, particularly where pulsation and vibration are a concern.
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 liquid-filled gauges feature brass or stainless steel components and a ventable top fill plug for pressure relief and ease of venting after installation.
Units are hermetically sealed for reliable operation in harsh or dirty environments, while reducing the chance of leaks and facilitating ease of refilling in the field.
