40 mm & 50 mm Liquid Filled Severe Service Gauge

Favorite

Marsh 40 mm and 50 mm Liquid Filled Severe Service Gauges are a family of liquid filled 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 40 mm and 50 mm Liquid Filled Severe Service 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. 

The liquid-filled gauges feature a ventable top fill plug and can be mounted on either a horizontal or vertical plane. 40 mm and 50 mm Liquid Filled Severe Service Gauges are hermetically sealed for reliable operation in harsh or dirty environments, while reducing the chance of leaks and ease of refilling in the field.
