Rosemount 1151DP5S22B4M4E8DFQ4

Core Performance & Industrial Application

The Emerson Rosemount 1151DP5S22B4M4E8DFQ4 is a smart differential pressure transmitter, range 5 (750 inH2O / 186.4 kPa), with HART digital output.

Output code S: 4-20 mA DC user-selectable linear or square-root flow output with superimposed HART digital signal.

Reference accuracy ±0.075% of calibrated span (1:1 to 10:1 turndown); 50:1 rangeability with smart electronics; 2-year stability 0.1%.

Modular mechanical/electrical design offers backward and forward compatibility with legacy 1151 install bases.

It is used for DP flow (orifice), level and filter differential measurement as spare replacement.
