J7648P Datasheet, PDF (2/6 Pages) List of Unclassifed Manufacturers – 40MM 50MM SEVERE SERVICE GAUGE

63MM SEVERE SERVICE GAUGE
• 3 Standard Mounting Options: LM, CB and U-Clamp
• Glycerine Filled
• Ranges to 10,000 psi
Marsh Instruments Liquid-Filled Gauges are designed to perform in rugged applications and harsh environmental conditions -
especially where pulsation and vibration are a problem. Liquid Filled Gauges offer a significant cushioning and dampening effect,
reducing pointer flutter and internal gauge damage; also lubricating the internals, and reducing corrosion.
All stainless steel Liquid Filled Gauges feature a ventable top fill plug for pressure relief and ease of venting after installation.
Pressure ranges are available through 10,000 psi, with high pressure ranges offering a Helical Bourdon Tube for longer gauge life
and increased durability. The hermetically sealed construction reduces the chance of leaks, and makes field filling an easy option.
Typical applications include refineries, chemical plants, offshore platforms, oil rigs, marine applications, general
industrial application and OEM processes.
