New Series 655A differential pressure transmitters are on the market for high static/low DP applications.
They’re designed for use where extreme overpressure and 0.25% accuracy and stability are required at ranges down to 3-in. wc.
These DP transmitters are manufactured to ensure symmetry between the HI and LO ports. Symmetry along with automated welding gives the instruments outstanding performance capabilities over time at high elevated line pressure, notes the maker.
Series 655A ports are welded 316 SST with an O-ring-free design for high cyclical applications, capillary filled systems, or applications where a guaranteed leak-free system is needed. Full transmitters data are free.
