The Model 534 System is a complete 3 axis fluxgate magnetometer packaged in a
rectangular/parallelpiped package of dimensions 0.75" x 0.75" x 2.75".
The package corners are rounded to enable the unit to fit inside a 1.0" diameter
cylinder. The system operates from one of two optional input voltages: regulated ±5 VDC
or unregulated ±7 to ±12VDC and consumes a total power of 200 mW.
The Model 534 provides 3 analog output voltages proportional to the magnetic field
magnitude in three orthogonal directions. Full scale output is ±4.0 volts; this voltage
represents a magnetic field of ±1.00 Gauss. Output scale factor is adjusted to an accuracy
of +0.1%. The system noise level is <3x10-6G RMS/Hz½.
As a magnetic compass, the Model 534 can provide direction accuracy to better than
0.1º. Some applications combine the Model 534 with a precision 3 axis accelerometer
to provide roll, pitch and yaw angles accurate to 0.1º. In magnetic anomaly detection
situations, the low noise level of the Model 534 enables 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 Model 534's to record
both field 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 external correction of the output
voltages to increase overall system accuracy.
Connection to the system is accomplished by means of six #26 gauge Teflon insulated wires with
a nominal length of 6".
