Description
The US Gauge Model 844 / 845 pressure gauge uses either a front flanged or U-clamp case, and can be flush mounted on instrument panels, pressure test stands, steam cleaners, sterilizers, and many other types of equipment. Where a minimum of space is available, the 844 U-clamp series is more desirable. When it is desirable to mount the gauge from the front of panel, the 845 front flanged series may be specified. All models use a unique one-piece plastic threaded ring and window that can be removed, permitting in-panel pointer adjustment. An optional stainless steel bourdon tube and socket is available in cases where the pressure medium is corrosive to copper alloys.
The gauge has copper-alloy wetted parts in a 2", 2-1/2" or 3-1/2" gauge size. It has a 1/8-27 or a 1/4-18 NPT brass connection, and meets ASME B40.100 Grade B accuracy ±3-2-3% of span. The bourdon tube for pressure ranges above 15 psi up to and including 1000 psi are phosphor bronze, soft soldered; 2000 and 3000 psi are phosphor bronze, silver soldered; and vacuum and 15 psi are beryllium copper, soft soldered. The gauge can also be customized for OEM applications.
