Micro Motion 4200 2-Wire Transmitter: Cost-Effective Coriolis Performance with Simplified Installation

Product Description:
The Micro Motion 4200 Transmitter redefines value in Coriolis measurement by delivering advanced performance within a proven, loop-powered 2-wire architecture. Engineered to significantly lower capital and operational expenditures, it shares power and signal over a single pair of wires, dramatically reducing installation complexity, cabling costs, and commissioning time. By offering the core benefits of Coriolis technology—including direct mass measurement, no moving parts, and wide turndown—without the need for additional power drops, the 4200 provides a robust, reliable, and financially smart solution for improving process control and product quality.

Key Features & Benefits:

• Dramatic Cost Reduction: The loop-powered 2-wire design eliminates the need for separate power cabling and associated infrastructure, substantially lowering upfront installation costs, ongoing energy consumption, and total cost of ownership compared to traditional 4-wire Coriolis meters.

• Simplified Deployment & Retrofit: Enables easy expansion into areas without readily available power and allows for the straightforward replacement of existing 2-wire flow devices (like vortex or DP meters) without incurring new power or cabling expenses, upgrading measurement capability with minimal disruption.

• Core Coriolis Performance: Delivers high-accuracy measurement for liquids, slurries, and gases, with mass flow accuracy up to ±0.10% and density accuracy up to ±0.0005 g/cc. Its robust design requires no straight runs or flow conditioning, ensuring reliable and repeatable operation.

• Integrated Intelligence & Diagnostics: Features an on-board data historian with an integrated real-time clock, which time-stamps all process data, alerts, and logs to provide a complete audit trail for troubleshooting. Smart Meter Verification Basic is included as standard, offering a quick assessment of meter health.

• Operational Flexibility & Safety: The multi-language graphical display can be rotated via software without removing the cover, facilitating viewing in any orientation and minimizing downtime associated with hot work permits in hazardous areas.

• Certified for Critical Applications: Certified for SIL 2 (single use) and SIL 3 (multiple use) safety applications per IEC 61508 and carries comprehensive hazardous area approvals (Class I Div 1/2, ATEX Zone 1/2, Intrinsically Safe, Explosion Proof), ensuring compliance in regulated environments.

• Configurable Output: While primarily a 2-wire HART device, it offers a licensable second channel (Channel B) that can be configured as an additional 4-20 mA, frequency, or discrete output, providing added flexibility.

Positioning Note:
The 4200 2-Wire Transmitter is strategically positioned as the most cost-effective and easiest-to-deploy entry point into the Micro Motion Coriolis ecosystem. It opens up Coriolis technology for a wider range of applications where budget, existing infrastructure (2-wire loops), or simplified installation are primary drivers. It is the ideal choice for modernizing legacy flow systems, greenfield projects aiming to minimize electrical costs, and any application where the superior accuracy and reliability of Coriolis measurement are desired, but a traditional 4-wire architecture is impractical or too costly.
