Subheading: Achieve Maximum Reliability in Vacuum and Distillation with a Compact, No-Piping Design
Eliminate complexity and potential failure points. The Rosemount 3051S Direct-Mount Absolute Pressure Transmitter integrates a true sealed vacuum reference into a robust, threaded housing that installs directly into your process. This revolutionary design is engineered for applications where space is limited, installation cost is critical, and measurement integrity relative to a perfect vacuum is non-negotiable
Key Selling Points:
【Eliminate Piping, Reduce Costs & Leak Risks】
Direct-Threaded Installation: Screws directly into the process via NPT or G-thread, completely removing the need for impulse piping, tubing, and fittings. This slashes installation time and material costs by up to 50%.
Inherently Leak-Resistant: With zero external impulse lines, the number of potential leak points is reduced to just one-the primary seal. This dramatically enhances safety and system integrity.
Ultra-Compact Form Factor: Ideal for OEM equipment, skids, and panels where space is at a premium.
【True Absolute Pressure Measurement】
Sealed Vacuum Reference: A permanent, evacuated reference cell ensures measurements are absolutely independent of local barometric pressure changes, weather, or altitude.
Critical for Process Consistency: Provides the precise data required to control boiling points in distillation columns and maintain precise vacuum levels, directly impacting product quality and yield.
Superior Performance in Vacuum: Maintains exceptional stability and accuracy even in low-pressure and deep vacuum environments.
【Uncompromising Emerson Quality & Support】
Robust Construction: Built with 316L stainless steel wetted parts to withstand corrosive and demanding process conditions.
Global Certifications: Certified for use in hazardous areas (ATEX, IECEx) and functional safety applications (SIL 2 per IEC 61508).
Worldwide Network: Backed by Emerson's global service and support infrastructure.
