Features
All Stainless Construction Laminated Safety Glass Lens Blowout Relief Grommet Fillable Case
Accuracy: *1.5% on 1 1/2“ gauges - ASME B40.1 Grade A
*1% on 2“ and 2 1/2“ gauges - ASME B40.1 Grade 1A
*1/2% on 4“ and 6“ gauges - ASME B40.1 Grade 2A
(* 10,000 PSI and below)
Adjustable pointer standard on 4“ and 6“ only
McDaniel designs and manufactures its gauges to minimize failure and to protect per-sonnel and property. The use of laminated safe-ty glass, rather than plexiglass or single strength glass, prevents dangerous pressure build-up in the case; the 2“ glass breaks at 60 psi, the 2 1/2“ at 40 psi, the 4“ at 15 psi and the 6“ at 8 psi. The brittle glass cracks uniformly and the laminate remains intact. Additionally, the laminated safety glass won't craze or discolor.
Every All Stainless Steel McDaniel gauge is designed to withstand:
0 300% full scale pressure without rupture of the bourdon tube.
0 130% full scale pressure without loss of accuracy.
0 15,000 cycles of pressure pulsation from 10% to 90% full scale at a rate of 60 times a minute. The gauge is allowed to rest for 5 minutes and then can have no greater error than 1% above it’s original accuracy as stated above; at any place on the dial.
Pulse/Vibration Protection
McDaniel offers liquid-filled gauges for appli-cations involving vibration or pulsation. Glycerin is an excellent damper of bourdon tube movement. Emersion of the entire measuring assembly in a protective liquid envelope pro-vides lubrication and shuts out corrosive or dirty atmospheres –– thereby minimizing wear of moving parts and prolonging gauge life signifi-cantly.
When you order a McDaniel fillable gauge you may choose to fill it yourself or you may order it factory-filled with the liquid of your choice. Thus, you can maximize inventory utility and minimize inventory cost.
Glycerin filling has a l
