Siemens® QBM3020-1D Air Duct Differential Pressure Sensor With Display

Product Id : 157434


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.

Product Description

Siemens® QBM3020-1D Air Duct Differential Pressure Sensor acquires differential, over and under pressure of air and nonaggressive gases if a high degree of measuring accuracy and quality is required. It is also suited for measuring volume flow using differential pressure since the output signal can be set to extracting-the-root.

Fields of Application

  • Measuring the slightest differential pressures in air conditioning ducts and ventilation.
  • Check air flows.
  • Maintenance free long-term stability
  • Monitor filters and control fans.
  • Pressure supervision in labs, production, and clean rooms.
  • For acquiring variable airflow in VAV plants on the supply and extract airside.
