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
