4 1/2" PROCESS PRESSURE GAUGES

The 41/2" Process Gauge is designed for those severe service applications where operator safety is a factor. This solid front gauge is equipped with a solid wall separating the indicating dial from the bourdon tube and a blow-out back which will release from the caseif the bourdontube should rupture. Available with phosphor bronze/brass, 316 stainless steel or monel internals,liquid-filled or dry construction, this gauge is ideally suited for the require-ments of the Process, Power and Chemical Industries. This high quality gauge offersthe benefit of field filling without any additional kits or accessories.
