Rosemount 1151 Pressure transmitter

With over five million transmitters installed worldwide, the Rosemount 1151 continues to offer industry leading
value. Changing customer needs and new technologies have driven product improvements, while advanced
manufacturing and testing processes have guaranteed product quality. Even today, the Rosemount 1151 is
world-reowned for proven field reliability and longevity.
Proven field performance and reliability
For over 35 years, the 1151 has provided the process
control industry with unsurpassed service and
reliability in even the harshest of environments. The
lasting customer preference results from a
combination of advanced technology, and a tradition
of field proven performance.
Commitment to continuous improvement
Through ongoing focus on continuous improvement,
±0.075% reference accuracy has been accomplished
as a result of manufacturing and engineering
enhancements. In addition, Smart electronics offer
rangeability to 50:1, reducing the number of
transmitters to specify, procure, and carry in
inventory. A modular design allows interchangeable
mechanical and electrical components, providing
backward and forward compatibility.
Application flexibility
The 1151 offers a variety of configurations for
differential, gage, absolute and liquid- level
measurements including integrated solutions for
pressure, level, and flow. High pressure models allow
static line pressures up to 4500 psi (310 bar).
Multiple wetted materials, as well as alternative fill
fluids ensure process compatibility. Smart, analog
and low-power electronics are available to meet
specific application requirements.
