Horizontal version
Low cost HORIZONTAL SOLID STATE advanced Pitch / Roll / Temperature compensated COMPASS / MAGNETOMETER system is built around a state of the art CMOS microcontroller utilizing AOSI’s proprietary algorithm on a 0.9″DIAM x2″ assembled PCB and sealed in a 1″ diameter x 5″ long tubular Aluminum non-magnetic enclosure with integrated bulkhead connector or water tight feed through.
The COMPASS PROBE outputs continuous heading, magnetic field, dual axis tilt and temperature data over the standard RS-232 and RS-422 and RS-485* or USB interfaces.
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 180 arcdeg.COMPASS/TILT probe is perfectly suitable for logging, bore hole profiling, antenna orientation, numerous navigation, research, training, construction, entertainment and other precision orientation, navigation and leveling applications.
The COMPASS PROBE is able to output multi-sensor information in NMEA-0183 mode and responds to numerous generally used commands.
Easy link through the Hyper Terminal Windows accessory facilitates custom calibration, hard iron compensation, data acquisition, data averaging, scan delay, dumping factor and data display. Probe is supplied with a mating 6 foot cable, demo software and manual. Manual can be downloaded from LIBRARY section.
The Compass Probe is also available in a special logging version EZ-PROBE-4L.
