Differential pressure sensors in the SDP800 series are the reliable solution for precise air flow measurement in the most demanding but cost-sensitive applications. The sensors are the result of more than 15 years of experience in measuring air flow to millions of HVAC systems, car engines and patients.



  • No offset, no zero-point drift, hysteresis free
  • Outstanding accuracy and long-term stability
  • Pressure range of up to ±500 Pa (±2 inch H2Ov/±5mbar)
  • Excellent accuracy and repeatability (even below 1 Pa)
  • Fully calibrated and temperature compensated (-20°C to +85°C)
  • For air and non-aggressive gases
  • Manifold or tube connection
  • Digital (I2C) or analog output


  • HVAC (heating, ventilation, air conditioning)
  • Gas boilers, pellet stoves and fuel cells
  • Filter monitoring
  • VAV control
  • Heat recovery
  • Medical (e.g. respiratory devices)
