Pressure Instruments

306 In-Line Manifold

Traditional in-line integral manifold that screws factory-direct to an in-line pressure transmitter (3051T / 3051HT / 2051T) or pressure gauge via NPT threads. Block-and-bleed, two-valve, or ASME B31-compliant two-valve configurations. 316 SST workhorse plus Alloy C-276 / Alloy 400 / Alloy 625 / Super Duplex SST options for aggressive service. Pairs with the R306 Enhanced (Pressure-Lock) variant for sites that need a rebuildable valve seat.

4051S Coplanar Scalable Pressure Transmitter

Emerson's next-generation flagship Coplanar pressure transmitter. Differential, gage, or absolute measurement with up to 0.025% span accuracy, 20-year stability, and 20-year limited warranty (Ultra performance). Optional Universal 800:1 rangedown consolidates inventory. HART 4-20 mA, optional dual integral relay switches, Bluetooth configuration, and large graphical display (built-in or remote up to 100 ft). Pairs factory-direct with the Rosemount R305 Pressure-Lock Manifold.

4088 MultiVariable Transmitter

Modbus multivariable transmitter measuring differential pressure, static pressure, and process temperature in one device. Designed for oil and gas production, custody transfer, and plunger-lift systems. Configure online or contact us for assistance.

R305 Enhanced Integral Manifold

Enhanced Integral Manifold with the Pressure-Lock valve and two-piece stem design — exclusive to the R305/R306 lines. 2-, 3-, or 5-valve Coplanar mount that bolts directly to a 3051C, 2051C, or 3051S transmitter. 316/316L SST body only with ½-14 NPT female process connections; PTFE or graphite packing; optional NACE-compliant wetted materials and P2 cleaning for special services.
