Rosemount 1151DP Transmitter

Core Performance & Industrial Application

The Rosemount 1151DP5S22M7E8R1DFQ4Q8 is a 1151DP differential pressure transmitter, range 5 (URL 750 inH2O / 186.4 kPa), S-code HART smart 4-20 mA with user-selectable linear or square-root output.

Reference accuracy ±0.075% of calibrated span (1:1 to 10:1 URL); two-year stability 0.1%; rangeability 50:1; M7 local indicator; E8 integral manifold valve; R1 process connection code.

Measures DP for orifice flow, tank level and filter differential; 316 SST isolating diaphragms; silicone fill; 1151DP hydrostatic test 3000 psi.

It serves as analog/HART field DP transmitter spare in process loops.
