Pressure Sensors, Flow Sensors and Switches
Reliable pressure and flow sensors for all HVAC systems.
Our wide range of pressure sensors and flow sensors combine well-proven technology and extensive testing to provide you with accurate, reliable, maintenance-free functionality. We offer sensors for measuring both pressure and differential pressure to meet the needs of the air and water side of HVAC systems.
Differential Pressure: Siemens Air Differential Pressure Sensors provide years of maintenance-free measuring accuracy. They deliver temperature-compensated sensor signals for registering airflow in HVAC systems and for measuring differential pressures in environmental, laboratory, and cleanroom applications.
Air Velocity: The QVM62.1 Air Velocity Sensor/Transmitter is used to control the air velocity to a constant value, balance out pressure.
- Integrated mounting bracket for simple installation
- Excellent long-term stability for maintenance free operation
- Calibrated and temperature-compensated measuring signal
- LCD display
- Graduated probe ensures maximum flow accuracy.
- Flow directional arrow provides for the most accurate reading.
- Connection cable provides mounting flexibility
