Series 677B Differential Pressure Transmitters are designed to measure pressures as low as 0.1 in w.c. with ±0.4% accuracy.

Use Series 677B for building energy management systems, environmental pollution control, oven pressurization, lab and fume hood control, HVAC and VAV applications.

The transmitter features 15 psid overpressure, reverse polarity protection and EMI/RFI protection. Internal regulation permits use with unregulated DC power supplies.

The NEMA 4 housing allows for versatile mounting locations and integral mounting tabs simplify installation.
Features
  • NEMA 4 housing enables a range of use outdoor or indoor where water is present
  • High accuracy at low pressure ranges provides exceptional measurement for insuring tight-control and minimizing costly out of specification conditions
  • Use with unregulated DC power permits easy access to electrical supply reducing costly power conditioning and wiring
