AUAV Dual Air Speed and Altitude Pressure Sensor

Amphenol All Sensors' AUAV series combines a high-accuracy differential pressure sensor with a barometric (altitude) pressure sensor in a single package. A unique dual ASIC compensation technique provides 18 bit calibration accuracy for exceptional high-resolution performance measuring both airspeed and altitude measurements simultaneously. This small, lightweight sensor is produced using a compact printed circuit board (PCB) module and is compatible with automated SMT assembly processes. The AUAV series provides a total error band (TEB) of less than 0.45% over the compensated range of -40°C to +85°C. Interfacing the flight control system is easily handled with available I²C and SPI output interfaces. AUAV is internally regulated and operates from a single supply voltage, ranging from 1.6 V_DC to 3.6 V_DC. The low-profile package is ideal where small-size packaging is required. The pressure interface is also made easy having only two small capillary tubes needed for easy connection in production.
