Leading a tradition of excellence
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-renowned for proven field reliability and longevity.
Proven field performance and reliability
For over 30 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, Model 3151 with +/- 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.

Liquid, gas, and vapor applications
Ranges
See Table 2 for ranges. Minimum span equals the upper range limit (URL) divided by rangedown. Rangedown varies with the output code See Table 1.
Outputs
Code S, Smart
4-20 mA dc, user selectable for linear or square root output. Digital process variable superimposed on 4-20 mA signal, available to any host that conforms to the HART® protocol.
Code E, Analog
4-20 mA dc, linear with process pressure
Code J, Analog
4-20 mA dc, square root of differential input pressure between 4 and 100% of input. Linear with differential input pressure between 0 and 4% of input.
Zero Elevation and Suppression
Output Code S, E
Zero elevation and suppression must be such that the lower range value is greater than or equal to the (-URL) and the upper range value is less than or equal to the (+URL). The calibrated span must be greater than or equal to the minimum span and less than or equal to the maximum span.
Output Code J
Zero is adjustable up to 10% of the calibrated flow span.
Span and Zero
Output Code S
Span and zero may be accessed with local adjustments or remotely through a HART-compatible Interface.
Output Codes E, J
Span and zero are continuously adjustable.
Power Supply
External power supply required. Transmitter operates according to the following requirements:
Output Codes S, E, J
12 to 45 V dc with no load
