3DR Dual pressure CAN sensor - R0011 
Our new dual pressure sensor features All Sensors' AUAV barometer + differential air pressure 2-in-1 sensor.
This sensor provides architectural changes that provide a significant improvement over their own DLVR series sensor, having more resolution and improved accuracy.
The AUAV series provides a total error band (TEB) of less than 0.65% over the compensated range of -30°C to +85°C. This part includes a pitot tube, flexible tubing, and a 4-pin JST-GH wire.
Optional pressure ranges and sensor types are available upon request.
