Differential Pressure Sensor Siemens QBM3020-1D accurately measures differential, over, and under pressure in air and non-aggressive gases where precision is essential. It operates using a silicon rubber membrane and a ceramic bar, generating linear or root-extracted signals calibrated and temperature-compensated for accuracy. The sensor includes a display for real-time monitoring and allows adjustable measurement ranges through a potentiometer, ideal for airflow and volume flow detection. Applications: HVAC-R, Clean Room, Data Center Cooling Systems, Laminar Flow, Building Pressure Control, Pharmaceuticals, Hospitals, Bio Labs, HVAC, Laboratory Exhaust Systems.
