We supply sensors designed to measure the air/water pressure in HVAC heating and cooling systems.

Our range also includes air/water differential pressure switches and sensors as well as air velocity and air flow sensors, switches and gauges.

The sensor outputs are active 0...10V or 4...20mA. The switch outputs are SPDT on/off.

All of our sensors are compatible with all common HVAC DDC and Analogue control systems.

Please refer to the relevant data sheets for detailed specifications.
