Real speed measurement up to 450 km/h!

With the speed sensor as an add-on to the UniLog 1 + 2 it is possible to measure and record airspeeds from 0 - 450 km/h. The speed is measured by measuring dynamic pressure (i.e. air pressure generated by the airspeed) and ambient air pressure. The speed measurement is carried out by measuring the dynamic pressure (i.e. the air pressure generated by the airspeed) and the ambient air pressure. The sensors can each be switched over in the measuring range from 250 to 450 km/h by means of a soldering bridge. By selecting the lower value, you can improve the resolution in the lower range. Since the dynamic pressure increases quadratically with speed, very low speeds are difficult to measure with this type of sensor. The sensible range of application therefore begins at about 30 km/h. Below that, of course, measurements are also taken, but the error and the noise are correspondingly greater.

The speed sensor consists of two parts:

  • The pitot tube is designed as a Prandtl tube. The ambient pressure is measured directly at the pitot tube via the ring-shaped holes. In this way, the system is independent of the pressure conditions in the fuselage (e.g. incoming cooling air).
  • Precision differential pressure sensor with connection to the UniLog. Power is supplied from the UniLog.

The connection between pitot tube and sensor is made via two thin silicone hoses.

  • Dimensions electronics: 17 x 15 x 15 mm plus hose connections.
