Solid State Logging Compass
AOSI's EZ-COMPASS-3AL LOGGING Compass incorporates a three-axis Magnetometer with tilt and temperature compensation and a onboard rewritable memory that allows independent storage of up to 20,000 readings and transferable to any PC. The 1.5"x2.0"x0.5" module weights about 11° and generates heading, pitch, roll, magnetic field and temperature over RS232 or RS422 ports by using all solid state components. Compass measures tilt angles up to +/-90 arcdeg and includes tilt linearization, hard and soft iron calibrations and high rate of throughput without any moving parts. 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 data transfer as far as two kilometers from the compass. Major uses include marine and land navigation, vehicle and structure positioning, construction, antenna and satellite tracking among others.
