Three-dimensional electronic compass FNN-3300 instruction manual

One. Features

1. The compass measures the planar geomagnetic field through a three-axis magnetoresistive sensor, and the two-axis tilt angle compensation.

2. High-speed and high-precision A / D conversion, magnetic field measurement accuracy of 100μGuass.

3. The compass has built-in temperature compensation to minimize the temperature drift of tilt angle and pointing angle.

4. The built-in microprocessor of the compass calculates the angle between the sensor and the magnetic north, and outputs a data frame in RS232 format. Optional RS485 and RS422 output.

5. With simple and effective user calibration instructions.

6. With pointing to zero correction function.

7. The shell structure is waterproof and non-magnetic. (Optional without shell)

8. Operating temperature range is -40 ° C to + 85 ° C. Storage temperature -55 ℃ to + 100 ℃.

two. Product application range

Electronic compass FNN-3300 can be widely used in aviation and navigation, communication radar, microwave orientation, offshore platform control, antenna installation and fixing, automatic control of drones and robots, and detection of traffic vehicles.
