AT2610-16A High Accuracy Barometer Module

General Description

The At module AT2610-16A precision digital-output pressure sensor uses smart sensor techniques to correct pressure readings for temperature and linearity, achieving a total error band of under 0.1% FS (0.016 PSI) over the -58 F to +185 F temperature range. The typical error band is 0.05% FS (0.008 PSI) over the -58 F to +185 F temperature range. Static accuracy is better than 0.002 PSI. The module contains an aerospace-grade silicon pressure sensor, sensor interface electronics, a 21-bit A/D converter, EEPROM calibration memory, and a sensor signal processor. Operating from an unregulated power supply, the module is designed for board mounting with 10-pin header connection. The module is media isolated and compatible with air and oils. The wetted materials are stainless steel and silicon. A parylene conformal coating protects the electronic circuitry.
