Product Description

Product Description

Rosemount 3051CG Differential Pressure Transmitter Baseplate: Comprehensive Technical Overview
Designed for Superior Stability, Flexibility, and Integration
1. Product Overview & Core Value Proposition
The Rosemount 3051CG Baseplate serves as the foundational mounting platform for Rosemount's 3051C series differential pressure (DP) transmitters. As part of Emerson's CoPlanar™ platform, it enables seamless integration with manifold valves, seal systems, and process connections while ensuring mechanical stability and measurement accuracy. Its design prioritizes:
Standardization: Unified mounting for 3051C/3051CG transmitters, reducing installation complexity.
Risk Mitigation: Minimizes mechanical stress on the sensor module during assembly/operation.
Lifecycle Efficiency: Compatible with legacy and future Rosemount accessories (e.g., valve manifolds, remote seals).

Modularity: Allows direct mounting of 3051CG transmitters without alignment adjustments. Supports traditional flange brackets (Option B2) or direct piping mounts (rtnews/1398.html).
Seal System Flexibility: Compatible with direct-mount seals, capillary assemblies, and flange-mounted remote seals (e.g., 1199 seal systems) for corrosive/clogging media 
(https://m.html/2025/0204/8036131074007027.shtm).
2.2 Robust Construction & Materials
Material Options:
Standard: 316L Stainless Steel (Code 2)
Corrosion-Resistant: Alloy C-276 (Code 7), Tantalum (Code 5) (rtnews/1313.html).
Pressure Containment: Rated for static pressures up to 2070 kPa (300 psi), with overpressure protection up to 4500 psi (subject to model restrictions) (rtnews/1398.html).
O-Ring Seal: Glass-filled PTFE (Code A) ensures leak-free performance in thermal-cyclic processes .
2.3 Sensor Protection & Stability Optimization
Isolation Design: Prevents bolt over-torque from damaging the sensor diaphragm during manifold assembly (documents/automation/reference-manual-rosemount-3051-pressure-transmitter-foundation-tm-fieldbus-protocol-en-76002.pdf).
Vibration Damping: Integrated ribs reduce process noise and mechanical resonance.
Thermal Stability: Maintains ±0.15% URL accuracy from -40°C to +85°C (with LCD option) 
(https://m.paper/250069818.html).
3. Installation System & Operational Efficiency
3.1 Valve Manifold Integration
Pre-Assembled Solutions: Factory-integrated with 3-valve or 5-valve manifolds (Options S5/S6), reducing field labor by 20% and eliminating leak points 
(https://m.html/2025/0204/8036131074007027.shtm).
Bolting Standards: Uses ASTM 316L stainless bolts (Option L4) for NACE MR0175 sour gas compliance (rtnews/1313.html).
3.2 Process Connection Versatility

Connection Type	Options	Applications
Direct-Mount	¼" NPT, G½, ANSI/DIN flanges	Pressure, level in open vessels
Remote Seal	Rosemount 1199 with capillary lengths 1-20m	High-temperature, viscous, or crystallizing media
Sanitary	Tri-Clamp, DIN 11851	Food, pharma, bioprocessing

3.3 Tuned-System™ Performance
Combines direct-mount (high-pressure side) and remote-seal (low-pressure side) configurations to:
Boost Response Time: 80% faster than balanced seal systems.
Accuracy Improvement: Up to 30% reduction in total measurement error
