PM277 Differential Pressure Monitor
PM277 Data Sheet

The PM277 converts differential air pressure to an analog output and provides a relay contact
  • Robust piezoresistive silicon pressure sensor for high accuracy and long life
  • Wide pressure range from 0.3 psi to 30 psi (2 kPa to 200 kPa)
  • Option for open collector transistor output instead of relay contact
  • Low range AC or DC voltage power supplies
Common applications include
  • Ventilation system monitoring
  • Pressure monitoring & control in clean rooms
  • Control of process air systems
