Dwyer 677B Series Differential Pressure Transmitters

Model: 677B Series

Designed to measure pressures as low as 0.1 in w.c. with ±0.4% accuracy. The transmitter features 15 psid overpressure, reverse polarity protection and EMI/RFI protection. The NEMA 4 housing allows for versatile mounting locations and integral mounting tabs simplify installation.


Dwyer 677B-11 Offers

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

Applications

  • Building energy management
  • Environmental pollution control
  • Lab and fume hood control
  • Variable air volume
