Description
The Siemens Building Technology QBM3230U2D Differential Air Pressure Sensor is a sensing part used to measure the pressure difference between two air points and convert it into an electrical signal for monitoring and control purposes in HVAC systems. It is used in air handling units, duct systems, and filter monitoring applications, where accurate air flow and pressure assessment are necessary under varying operating conditions. It plays a vital role in supporting system regulation by detecting changes in air resistance and helping maintain stable ventilation performance. It operates within systems and provides reliable differential pressure for control automation.
