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. Transient Protection (Option Code T1) All Models: Meets IEEE C62.41, Category B 6 kV crest (0.5 μs - 100 kHz) 3 kV crest (8 × 20 microseconds) 6 kV crest (1.2 × 50 microseconds) Meets IEEE C37.90.1, Surge Withstand Capability SWC 2.5 kV crest, 1.25 MHz wave form General Specifications: Response Time: < 1 nanosecond Peak Surge Current: 5000 amps to housing Peak Transient Voltage: 100 V dc Loop Impedance: < 25 ohms Applicable Standards: IEC61000-4-4, IEC61000-4-5; Zero and Span Adjustment Requirements (HART and Low Power) Zero and span values can be set anywhere within the range limits stated in Table 1 and Table 2. Span must be greater than or equal to the minimum span stated in Table 1 and Table 2. 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.
