Product Description

Siemens QBM3020 Differential Pressure Sensor is used to acquire differential, over and under the pressure of air and nonaggressive gases in applications where a high degree of measuring accuracy and quality is essential. Siemens Differential Pressure Sensor will be appropriate for measuring volume flow via differential pressure since the output signal can be set to extracting the root.

Features Of Siemens Differential Pressure Sensor:

  • The high degree of measuring accuracy.
  • Adjustable characteristic curve (pressure-linear or extracting-the-root).
  • Zero-point adjustment
  • Simple and fast mounting thanks to integrated fixing angle bar in the housing
  • Maintenance-free thanks to excellent long-term stability
  • Calibrated and temperature-compensated measuring signal
  • Supplied with plastic tubing
  •  Very short response time
