The Rosemount 2051TG4A2B21KS1E1M5P8C4Q4QTQ15+1199WDA95ARTW32DAA54Q15 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 2051TG4A2B21KS1E1M5P8C4Q4QTQ15, integrated with the 1199WDA95ARTW32DAA54Q15 Remote Diaphragm Seal, represents a precision-engineered solution for demanding pressure measurement applications. This assembly is designed to deliver exceptional operational integrity in processes where the process fluid must be isolated from the transmitter element. The 2051TG model provides gauge pressure measurement with a robust output signal of 4–20 mA, enhanced by a digital signal based on the HART® Protocol. This combination ensures high-fidelity data transmission and seamless integration into existing Distributed Control Systems (DCS) or Asset Management platforms. The remote diaphragm seal configuration is specifically engineered to mitigate common process challenges such as high temperatures, corrosive media, or viscous fluids, ensuring reliable measurement without compromising the sensing element.
Key Features & High-End Benefits
This configuration is built for process optimization and long-term reliability. The DA material selection for the isolating diaphragm provides superior corrosion resistance in aggressive chemical or hydrocarbon environments, extending service life and reducing unplanned maintenance. The wide measurement range, spanning from -14.7 to +4000 psi (-1.0 to +276 bar) for gauge and 0 to 4000 psia for absolute, offers exceptional versatility for low-pressure vacuum applications up to high-pressure refining processes. The HART® Protocol capability allows for remote configuration, diagnostics, and multivariable data access, enabling predictive maintenance strategies and reducing manual field intervention. The remote seal design eliminates dead-legs and minimizes clogging risks, ensuring process fluid integrity and consistent measurement accuracy even in harsh or sanitary applications. Furthermore, the integrated features (M5, P8, C4, Q4, QT, Q15) provide enhanced output stability, advanced diagnostics, and robust electrical transient protection, which collectively safeguard against process upsets and
