Siemens® QBM3020-1D Air Duct Differential Pressure Sensor acquires the differential pressure using a silicon rubber membrane and ceramic bar. Depending on the type of sensor, the sensor generates a linear or extracting-the-root signal, which is calibrated and compensated for temperature. The individual adjustment of the pressure measurement range for extracting the-root sensor is done by means of a potentiometer
Applications: HVAC, Pharmaceuticals, HVAC-R, Hospitals, Laminar Flow, Clean Room, Bio Labs.
