Rosemount Pressure Transmitter 3051

Detailed Product Description

Rosemount 3051 the standard in pressure measurement.
Industrys best-in-class total performance
of ±0.15%
Total performance is the true measure of real-world
transmitter performance. Using superior sensor
technology and engineered for optimal performance,
the 3051 delivers unprecedented ±0.04% reference
accuracy, resulting in total operating performance of
±0.15%. Superior total performance equates to
reduced variability and improved plant safety.
Installed five-year stability of ±0.125%
Transmitter stability is a critical measure of
transmitter performance over time. Through
aggressive simulation testing beyond standard IEC
770 testing, the 3051 has proven its ability to
maintain performance over a five year period under
the most demanding process conditions. Superior
transmitter stability reduces calibration frequency to
save operation and maintenance costs.
Unmatched dynamic performance
In dynamic applications, speed of measurement is as
important as repeatability. The 3051 responds up to
eight times faster than the typical pressure
transmitter to detect and control variations quickly
and efficiently. Superior dynamic response yields
more accurate measurements to reduce variability
and increase profitability.
Coplanar platform enables complete point
solutions
The versatile Coplanar platform design enables the
best process connection for pressure, flow and level
applications. Right out of the box, the solution arrives
factory calibrated, pressure-tested, and ready to
install. Only the 3051 has a flexible design to reduce
engineering and inventory costs.
Advanced PlantWeb Functionality
The 3051 powers the PlantWeb
architecture by delivering the best
sensor and transmitter, best installation
practices, and best in class field
intelligence. One component is the
enhanced diagnostic capabilities in
FOUNDATION fieldbus that provide an increase in
process visibility, enabling proactive maintenance,
improving process availability and plant productivity.
PERFORMANCE SPECIFICATIONS
Total Performance is based on combined errors of reference accuracy, ambient temperature effect, and static pressure effect.
This product data sheet covers both HART and fieldbus protocols unless specified.
Conformance To Specification (±3σ (Sigma))
Technology leadership, advanced manufacturing techniques and statistical process control ensure specification conformance to at least ±3σ.
Vibration Effect
All Models
Measurement effect due to vibrations is negligible except at
resonance frequencies. When at resonance frequencies, vibration
effect is less than ±0.1% of URL per g when tested between 15
and 2000 Hz in any axis relative to pipe-mounted process
conditions.
Power Supply Effect
All Models
Less than ±0.005% of calibrated span per volt.
RFI Effects
All Models
±0.1% of span from 20 to 1000 MHz and for field strength up to 30
V/m.

Service
Liquid, gas, and vapor applications
420 mA (Output Code A)
Output
Two-wire 420 mA, user-selectable for linear or square root
output. Digital process variable superimposed on 420 mA
signal, available to any host that conforms to the HART protocol.
Power Supply
External power supply required. Standard transmitter (420 mA)
operates on 10.5 to 55 V dc with no load.
Load Limitations
Maximum loop resistance is determined by the voltage level of
the external power supply, as described by:
FOUNDATION fieldbus (output code F) and
Profibus (output code W)
Power Supply
External power supply required; transmitters operate on 9.0 to
32.0 V dc transmitter terminal voltage.
Current Draw
17.5 mA for all configurations (including LCD display option)
FOUNDATION fieldbus Function Block Execution Times
FOUNDATION fieldbus Parameters
Standard Function Blocks
Resource Block
Contains hardware, electronics, and diagnostic information.
Transducer Block
Contains actual sensor measurement data including the sensor
diagnostics and the ability to trim the pressure sensor or recall
factory defaults.
LCD Block
Configures the local display.
2 Analog Input Blocks
Processes the measurements for input into other function
blocks. The output value is in engineering units or custom and
contains a status indicating measurement quality.
PID Block
Contains all logic to perform PID control in the field including
cascade and feedforward.
Backup Link Active Scheduler (LAS)
The transmitter can function as a Link Active Scheduler if the
current link master device fails or is removed from the segment.
Advanced Control Function Block Suite (Option Code A01)
Input Selector Block
Selects between inputs and generates an output using specific
selection strategies such as minimum, maximum, midpoint,
average or first good.
Arithmetic Block
Provides pre-defined application-based equations including flow
with partial density compensation, electronic remote seals,
hydrostatic tank gauging, ratio control and others.
Signal Characterizer Block
Characterizes or approximates any function that defines an
input/output relationship by configuring up to twenty X, Y
coordinates. The block interpolates an output value for a given
input value using the curve defined by the configured
coordinates.
Integrator Block
Compares the integrated or accumulated value from one or two
variables to pre-trip and trip limits and generates discrete output
signals when the limits are reached. This block is useful for
calculating total flow, total mass, or volume over time.
FOUNDATION fieldbus Diagnostics Suite (Option Code D01)
The 3051C FOUNDATION fieldbus Diagnostics provide Abnormal
Situation Prevention (ASP) indictation. The integral statistical
process monitoring (SPM) technology calculates the mean and
standard deviation of the process variable 22 times per second.
The 3051C ASP algorithm uses these values and highly flexible
configuration options for customization to many user-defined or
application specific abnormal situations. The detection of
plugged impulse lines is the first available predefined
application.
