SERIES 655A DIFFERENTIAL PRESSURE TRANSMITTER

Description

Dwyer Instruments, Inc., the preferred source for your complete range of practical and affordable instrumentation, is announcing the release of its NEW SERIES 655A DIFFERENTIAL PRESSURE TRANSMITTER.
    Series 655A Differential Pressure Transmitters are designed for high static/low DP applications designed especially for the End Users and OEM’s where extreme overpressure and high performance of 0.25% accuracy and stability are required at ranges down to 3? w.c.
    Every 655A Series is built using advanced manufacturing techniques to ensure symmetry between the HI and LO ports. Symmetry, along with automated welding gives these differential pressure transmitters excellent performance and reliability over time at high elevated line pressure.
    The 655A Series transmitter pressure ports that are all welded 316 SST with an O-Ring free design making it ideal for high cyclical applications, capillary filled systems, or applications where a guaranteed leak free system is needed.
