submersible miniature version
High reliability submersible advanced pitch/roll compensated COMPASS / MAGNETOMETER system is built around a state of the art CMOS microcontroller utilizing AOSI’s proprietary algorithm on a 0.9″ x 2″ assembled PCB with a total height including tilt sensing elements of less then an inch.
Packaged in a marine grade black anodized cylindrical aluminum housing the unit outputs continuous heading, field, dual axis tilt and temperature data over the standard RS-232 or RS-422 or RS-485 interface at depth up to 3500 meters. The AZIMUTH is generated from a 3 axis semiconductor magnetometer with 12 bit ( 0.08 deg ) resolution. The LINEAR tilt information is available with 12 bit resolution for up to +-180arcdeg in roll and +-90 deg in pitch.
COMPASS/TILT module is perfectly suitable for numerous underwater navigation, research, training, construction, entertainment and other precision orientation, navigation and leveling applications. Bottom exterior surface is calibrated for accurate zero level
The COMPASS is able to output heading information in NMEA-0183 and local LCD modes. Easy link via Hyper Terminal Windows accessory facilitates custom calibration, hard/soft iron compensation, data acquisition, data averaging, and data display. EZ-COMPASS-4-DIVE-M is supplied with a mating connector molded to 2 feet cable. Custom cable length are available and are quoted upon request. Compass can be supplied in a Logging version EZ-COMPASS-4L-DIVE-M. Manualcan be downloaded from the LIBRARY section.
