2 63MM LIQUID FILLED BRASS GAUGES Ranges to 0,000 psi Field Fillable Rugged One Piece Construction 63mm Case Size Marsh Instruments Brass Case liquid filled gauges are designed to perform in severe applications. When pulsation and vibration are a problem, this one piece forged brass gauge is up to the task. Liquid filling lubricates the movement, protects the gauge internals, and reduces pointer flutter. The hermetically sealed construction reduces the chance for leaks, and makes field filling an easy option. This product features a vented top fill plug for continuous pressure relief. Typical applications include power units, robotics, pumps, compressors, hydraulics, as well as die cast machinery, marine, and automotive applications. 63MM LIQUID FILLED BRASS Size 63mm Case Material Forged Brass Internals Copper Alloy Mounting / Case Style LM Connection Scale Standard psi/kpa 0 to W9005 to 30 psi W902 to 60 psi W904 to 00 psi W906 0 to 5 psi W to 30 psi W to 60 psi W to 00 psi W to 60 psi W to 200 psi W to 300 psi W to 400 psi W to 600 psi W to,000 psi W to,500 psi W to 2,000 psi W to 3,000 psi W to 5,000 psi W to 6,000 psi W to 7,500 psi W to 0,000 psi W MM LIQUID FILLED BRASS GAUGE OPTIONS OPTION SUFFIX AVAILABLE ON MODELS Fill Medium Dry (no fill) Standard All ranges Glycerine Add suffix P Silicone (SL) Add suffix PI Liquid Filled ASME Grade ±2//2% (% of range across middle half of scale) CASE SIZES 63mm diameter (2.62") Forged Brass (one piece case & socket) S LM Lower Mount with screw on brass ring Copper alloy Brass 0 to, Compound 30" to 00 psi, 5 to 0,000 psi Dual scale psi and kpa Aluminum, black painted Acrylic FILL MEDIUM See Options VENT Rubber plug with snip-off feature 2.62 [66.6].20 [30.5] 2.9 [55.7].28 [7.] 27

Accuracy is ±0.5% of full span. A highly polished integral mirror is positioned between the two graduation arcs on the dial face. The knife-edge pointer is reflective so that, when the pointer and its reflection are in alignment, parallax is virtually eliminated and a true dial reading is assured. Typical applications include test stands, aviation ground support, petroleum chemical, utilities, industrial vessels and panel builder.
