This speed sensor is designed to work with the UniLog 1 & 2. It is capable of measuring and recording flight speeds from 0 - 450 km/h (0-279mph). The speed measurement is determined by measuring and comparing back pressure (the air pressure generated by the airspeed) and the ambient air pressure.
The sensor speed range can be changed from 250 to 450 km/h to 600 to 1000 km/h by closing a solder bridge on the sensor board; however, the sensor resolution will be reduced.
This sensor is less sensitive at speeds below approx 30 km/h (18 mph). The sensor will still record air speeds but error and noise will be present in the returned data. Speeds above 30 km/h (18mph) will not be an issue as dynamic air pressure increases quadratically.
The speed sensor consists of two components:
|Sensor Dimensions||17x15x15mm (.66x.59x.59in)|
|Pitot Tube Dimensions||65mm Long - 4mm OD (2.55x.15in)|
|Pitot Tubing Length||1118mm (44in)|
|System Weight||16.2g (.57oz)|
