Marsh Products

• Rugged ABS Case
• Ultrasonically Welded Acrylic Window
• Hermetically Sealed
• Ranges to 5,000 psi
• Dry or Liquid Filled Marsh

Marsh Instruments' Severe Service line features a regged impact and corrosion resistant ABS case gauge that is hermetically sealed. It is available dry or liquid filled. The liquid filling dampens the damaging effects of pulsation and vibration common to many hydraulic systems. it also lubricates the internals and reduces corrosion. The ultrasonically welded acrylic window and two piece socket design ensure superior, leak free performance.

• 3 Standard Mounting Options: LM, CB and U-Clamp
• Pressure Ranges to 5,000 psi/35,000 kPa
• ASME Grade B accuracy

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 vent top fill plug for pressure relief and ease of venting after installation. pressure ranges are available through 20,000 psi, with high pressure ranges offering a helical bourbon tube for longer gauge life and increased durability. The hermetically sealed construction reduces the chance of leaks, and makes field filling an easy option.

• Brass or Stainless Steel Internals
• Field Fillable
