The Rosemount 2051TG2A2B21BS1HR7B4I1M5DOV5C4P1+1199WDB59AFFW71DA00 remote diaphragm seal ensures accurate process control with its 4–20 mA with digital signal based on HART® Protocol and proven performance architecture.
The Rosemount 2051TG2A2B21BS1HR7B4I1M5DOV5C4P1+1199WDB59AFFW71DA00 represents a pinnacle of precision pressure measurement, integrating a high-performance remote diaphragm seal system. Designed for demanding process environments, this configuration delivers a 4–20 mA output with a superimposed digital signal based on the HART® Protocol, ensuring seamless integration into existing distributed control systems (DCS) and asset management architectures. The unit is engineered to isolate the sensing element from corrosive, viscous, or high-temperature media, thereby preserving measurement accuracy and extending operational lifecycle. With a calibrated measurement range spanning from -14.7 to +150 psi (-1.0 to +10.3 bar) for gauge applications, and 0 to 150 psia (0 to 10.3 bar) for absolute references, this solution is optimized for low-pressure differentials and critical vacuum-to-moderate pressure processes.
Key Features & High-End Benefits
Advanced HART® Communication & Diagnostics: The integrated HART® Protocol enables bidirectional digital communication, allowing for real-time process variable interrogation, remote configuration, and predictive diagnostics. This facilitates proactive maintenance scheduling, reducing unplanned downtime and enhancing operational integrity.
Corrosion-Resistant Diaphragm Material (DA): The selection of Material DA (typically Hastelloy C-276 or equivalent) provides exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking in aggressive chemical and hydrocarbon environments. This ensures long-term stability and minimizes wetted-part degradation, a critical factor for process optimization in harsh upstream and downstream applications.
