Model 520/520C

3-Axis Fluxgate Magnetometer System (150-0520)
Model 520/520C

The Applied Physics Systems Model 520 fluxgate magnetometer measures the field simultaneously along three orthogonal directions and is displayed on three front-panel 3-1/2 digit liquid crystal displays.

The Model 520 Fluxgate System can be employed to measure time variances as well as static fields. The system frequency response is flat from DC to 250 Hz, enabling measurement of power line generated fields, biologically generated fields and other small, time-varying fields.

The Model 520 and 520C Fluxgate Systems consist of a magnetic field measuring probe connected by a 15-foot interconnect cable to a power supply and electronic readout console. The small probe size enables magnetic measurements to be made in restricted spaces.

Model 520C Offset Capability
In addition to the features of the Model 520, the 520C adds
precision 3-axis offset capability. This capability enables the
nulling out of steady fields on all axes up to 10-4 T (1000 mG) with
no degradation in the instrument drift or noise level. This feature
is essential when measuring small field changes in the presence
of a large static field. This application can be used, for example,
to test materials for small magnetic impurities or measure small
changes in the Geomagnetic field.
