Rosemount 1151GP7 Gauge Transmitter

Core Performance & Industrial Application

The Emerson Rosemount 1151GP7S22B7M7E8L4DFQ4 is the smart gauge pressure transmitter, range 7 (0-300 psi / 2068 kPa), with HART output code S.

Output 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%.

Supply 12-45 VDC no-load; modular mechanical/electrical design with backward/forward compatibility.

It is used for gauge pressure measurement and spare replacement on legacy 1151 loops.
