Detailed Product Description
LP***0 three-axis digtal compass
First, Characteristics of
the Product
u Using the three-axis magnetoresistive sensor to
measure the spatial magnetic field with the two-axis title
compensation. u Built-in soft magnetic compensation.
u High-speed and High-precision A/D conversion;
measuring accuracy of the magnetic field is **0μ Guass.
u Simple and effective user’s calibration instructions.
u Zero pointing correction. u The range of
working temperature is between **0°C and **0°C, and the storage
temperature is between **0°C and ***0°C. Second, description
of the product LP***0 compass sensor used are: three-dimensional
and two-dimensional angle sensor magnetoresistive sensor. Among
them, the magnetoresistive sensor measuring Earth's magnetic field,
inclination sensor compass attitude. Output point is the compass
point north axis in the horizontal plane of projection and magnetic
north line of the angle between the ground projection. As the
magnetic compass is based on principles of magnetic heading angle
calculated to reduce or eliminate the interference of its output
accuracy of the magnetic field is applied in the project must be
addressed. Affect the precision electronic compass orientation of
factors, such as the magnetic sensor installation error, inherent
magnetic compass device data acquisition and conversion error
(collectively referred to as electrical error), the non-existence
of multi-axis orthogonal magnetic sensor error, interference caused
by magnetic field Luo poor. For the installation error, electrical
error, non-orthogonal error, you can improve the design,
manufacture and installation of technology and other measures to
eliminate or weaken its compass heading accuracy. Use of the
environment caused by ferromagnetic media in magnetic field caused
by magnetic interference of Compass is a compass heading accuracy
of the largest and most difficult to control. In the absence of
interfering magnetic field, compass rotated in the horizontal
plane, the output of the (Hx-Hy) ideal curve is a center of the
circle in the coordinate origin of the perfect circle, see figure
below; hard iron interference resulting from a permanent magnet or
magnetic metal, such interference with the compass fixed relative
position, in the compass of the output value of adding a fixed
value, the compass rotated in the horizontal plane, the output of
the (Hx-Hy) curve is eccentric, see chart below; soft iron
interference generated in the Earth's magnetic field and near the
magnetic compass of any interaction between the degree of its
interference with the direction of the compass. In general, by the
soft magnetic interference, the compass level rotated, the output
of the (Hx-Hy) curve is the ellipse, see the figure below.
