Applications

The top is equipped with a filling plug and an internal compensation diaphragm, which can be filled on site. The liquid-filled safety pressure gauge has shock resistance and damping properties, which can prevent damage to the inside of the pressure gauge due to vibration, and can also lubricate internal components and reduce corrosion.

Description

The 4-1/2" 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 case if the bourdon tube 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 requirements of the Process, Power and Chemical Industries. This high quality gauge offers the benefit of field filling without any additional kits or accessories.
