Emerson Rosemount 3051 DP GP TG CD Smart Pressure Transmitter Differential Gauge Measurement for Process Control

The blue transmitter you see on pipes in every refinery, chemical plant and power station

Walk into any old plant and half the pressure transmitters are still 3051s from the 90s – they just keep working. New ones have the same coplanar design but better electronics, HART or Foundation Fieldbus, and local display. Instrument guys like them because the wiring is the same as the old ones, the calibration procedure hasn’t changed, and spare parts are everywhere. It measures pressure, level, flow – whatever you need.

• Coplanar flange – easy to mount, no leaks
• Local zero and span buttons – adjust without handheld
• Big LCD display on smart versions
• 4–20 mA HART – talks to every DCS
• Stainless diaphragm – handles almost anything
• Works from -40 °C to +120 °C without drama

• Process lines in refineries
• Boiler drum level
• Tank level and interface
• Flow with orifice plates

Q: Do you still make the 3051?
A: Yes – new units ship every day from Chanhassen.

Q: Can I replace my old 1151?
A: Yes – same manifold holes, same wiring.
