Dwyer Series 655A 316 Wet Differential Pressure Transmitter

Dwyer Series 655A 316 Wet Differential PressureTransmitter

• 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 procedures give these differential pressure transmitters excellent performance and reliability over time at high elevated line pressure.
• Each unit includes a 6-point NIST certificate of calibration which demonstrates the unit's high level of performance.
