EM-8652

Introduction

Use the PASPORT 2-Axis Magnetic Field Sensor in conjunction
with a PASPORT interface to measure magnetic field strength
simultaneously along two perpendicular axes.

The sensing elements are two Hall Effect devices oriented per­pendicularly to one another and located at the end of the sensor’s
probe. The sensor measures the magnetic field in the Axial and

Perpendicular directions as illustrated. Two white dots on the
probe mark the positions of the sensing elements.

Setup

Connect the sensor to a PASPORT interface, either directly or
using the included extension cable. If you will be using a com­puter, connect the interface to it and start DataStudio or
EZ-Screen software.

Optional: If you have a zero-gauss chamber (part EM-8652),
insert the probe into the chamber and press the Tare but­ton on the sensor to zero both measurements. For
greatest accuracy, tare the sensor in this way
after it has been connected to a powered
interface for a few minutes.

Note: If you do not have a zero-gauss chamber, pressing the Tare button
may result in a small offset to subsequent measurements due to the
earth’s magnetic field. To “undo” the tare, briefly disconnect the sensor
from the interface.

Measuring Magnetic Field

In the software or on the interface, start data collection to begin
recording magnetic field strength along both axes in units of
gauss (G). Position the sensing elements (marked by white dots)
at the location to be measured and orient the sensor with the field
lines.

Note: For more information about using your PASPORT interface, refer to
the documentation that came with it. For instructions on using DataStudio,
press F1 or open the Help menu.

strengths on a graph display. As you change the angles of the
sensing elements relative to the earth’s field, you will see the
measurements vary.

For a more quantitative study, use the included sensor handle to
mount the magnetic field sensor on a rotary motion sensor (part
PS-2120) and record field strength as a function of angle.

Magnetic Field of a Coil

Use the sensor to measure the field of a coil as a function of cur­rent through the coil or position within the coil. Rotate the sensor
to find the direction of field lines at various locations near the
coil.

Resolution and Sampling Rate

The sensor uses dynamic variable over-sampling to achieve the
best resolution possible for a given sampling rate. At the default
sampling rate of 10 Hz, the resolution is 0.01 G. To improve the
resolution, set a lower sampling rate in the software or on the
interface. The best resolution occurs when sampling at 1 Hz or
slower.

Hardware Mounting

The sensor includes a captured ¼-20 nut, which you can use to
fasten it to the included sensor handle, a rod, or other apparatus.
The sensor handle can be used to mound the magnetic field sen­sor on a rotary motion sensor (part PS-2120). With the sensor
mounted in this way, it may be necessary to use the included
extension cable to connect the interface.

Suggested Activities

Maximum Sampling Rate 1000 Hz
