PSS-8M

Small Air Data Computer Board PSS-8M for OEM Integration

The PSS-8M is a small and very accurate air data computer for OEM integration. It provides pitot-static pressure and temperature measurement in a single device. The PSS-8M is based on the well known PSS-8. Pitot-Static System PSS-8M has the following key features:

  • Measures static pressure, impact pressure and temperature
  • Outputs fully calibrated air data at 100Hz
  • Small, light and durable
  • High accuracy
  • Affordable

PSS-8M Air Data Computer
