QBE63-DP...

for neutral and mildly corrosive liquids and gases

Differential pressure sensor, suitable for gases and liquids, for the measurement

of positive and negative pressures and pressure differentials in HVAC systems.

• Hall-effect transducer technology

• Highly resistant to positive pressure

• Simple, robust construction for highly reliable operation

• For neutral and mildly corrosive liquids and gases

• Supply voltage AC 24 V or DC 20...30 V

• DC 0...10 V output signal

• Female-threaded G

/8" connection

Use

The QBE63-DP... differential pressure sensors are particularly suitable for use in HVAC

systems for continuous monitoring of the level or flow rate of neutral or mildly corrosive

gases or liquids.

The pressure being monitored acts on a measuring system comprising a diaphragm,

permanent magnet and Hall-effect transducer. The measured pressure is converted

electronically into a linear DC 0 ...10 V output signal.
