Using the two-axis magnetoresistive sensor to measure the plane geomagnetic field
High-speed and -precision A/D conversion
Measuring accuracy of the magnetic field is 100μGuass
Built-in microprocessor computing sensor which forms an angle with the magnetic north, RS232 format of data frame output
Working temperature: -40°C and +80°C
Storage temperature: -50 and +100°C
Description:
The product has two built-in cross-field sensors, and has two series of production
One is of high accuracy and the other low accuracy
The high accuracy product adopts a 16-bit A/D converter and the precision of the magnetic field is around 1Gs after calibration
While the low accuracy product has the characters of low cost and good stability, so it is suitable for mass production
The correctional instructions of the calibration and direction are simple and effective
The compass can eliminate the effect of the fixed magnetic field interference on the non-positive spin pointing after circling the surface or the plane of measurement once
But if the interference is too large or changes, the effect can not be removed
For the occasion requiring accuracy, to provide little interference environment is a necessary condition to ensure the accuracy
