Magnetic Anomaly Detection
The CXM113 is a complete 3-axis
fluxgate magnetometer system
packaged on a PC board of
dimensions 2.5" x 2.5" x 0.75"
(6.4cm x 6.4cm x 1.9cm). The system
operates from an input voltage of
± 5 VDC. Current consumption is
28 mA @ +5 V and 7 mA @ -5 V. The
system is connected by 6” long flying
leads.
The CXM113 provides 3 analog
output voltages proportional to the
magnetic field magnitude measured
in three orthogonal directions. The
full-scale output is ± 4.0 volts;
representing a magnetic field of
± 1.00 Gauss. Output scale factor
is adjusted to an accuracy of 1%.
The system noise level is <1x10-6
Gauss rms/Hz½. As a magnetic
compass, the CXM113 can provide
direction accuracy better than 0.1º.

For magnetic anomaly detection
applications, the low noise level of the
CXM113 allows very small magnetic
signatures to be measured. This
enables signal detection at a large
distance from the anomaly being
measured. Range to the anomaly
can be measured by using several
CXM113s to record both field
magnitude and field gradient. Range
is proportional to the quotient of
these quantities.
A calibration sheet is provided with
each unit giving data on zeros, scale
factors, and orthogonality constants
for each axis. This data enables an
external correction of the output
voltages to increase overall accuracy.
