AOSI’s newest EZ-COMPASS-3AL LOGGING Compass incorporates a three axis Magnetometer with tilt and temperature compensation and a high capacity integrated logger that allows independent storage of up to 20000 measurements, which are easily transferable to any PC.

The 1.5” x 2.0”x 0.5” module weights about 11gr and outputs heading, pitch, roll, magnetic field and temperature over RS232 and RS422/RS485 ports by using all solid state components. Compass measures tilt angles up to +-90 arcdeg (+-180 optional) and includes tilt linearization, hard and soft iron calibrations. EZ-COMPASS-3AVL is a vertical version and EZ-COMPASS-3AHL is the horizontal version.

Both versions fit 0.9” diameter openings and are able to provide accurate directional and inclination drilling information for almost any drilling assignment.

Integrated RS-422 allows long distance (two kilometers) data communication. Major uses include marine and land navigation, vehicle and structure positioning, construction, antenna and satellite tracking among others.
