Basic Hall Effect Probes |
These probes are designed for older style Gaussmeters and Teslameters and are supplied with a "Calibration number" and printed calibration data for each measurement range. They can be used with the following Model numbers: 7300 Series, 750, 750A&D, 904, 906/906A, 912 and 915 Gaussmeters or Teslameters. |

Description
Magnetic Instrumentation, Inc. manufactures Hall Effect Probes in a wide range of styles
and sizes. Probes are supplied with magnetic, electrical, temperature stability and
calibration data for each measurement range.
Transverse (Flat) Probe
Transverse Probes are used to measure magnetic fields perpendicular to their flat
surfaces, and are available in thicknesses of 0.015 inch (.038 cm) to 0.080 inch (.203
cm). The Model 025 and Model 039 Probes have fiberglass/epoxy sleeves protecting the
sensitive Hall element.
Axial Probes
Axial Probes are used to measure magnetic fields parallel to the probe handle,
such as the field in a solenoid. The Hall element is located at the tip of the Probe. The
Axial Probes are available in diameters of 0.098 inch (.248 cm) to 0.312 inch (.729 cm).
Ruggedized Probes
Ruggedized (R) Probes styles are available for use in harsh environments. They
are enclosed in brass for protection against damage.
Probes for Special Application
Magnetic Instrumentation, Inc. can manufacture special Probes to satisfy magnetic
measuring requirements not covered by our standard Probes. Contact our magnetics
applications engineers for assistance.
High Field Probes
High Field Transverse and Axial Probes are available for measurement of fields up
to 100 Kilogauss (10 Tesla).
Temperature Characteristics
The temperature characteristics will vary slightly between individual Probes and
Probe types. The maximum change that can be expected is approximately .08% per ºC. All
Probes may be used in the temperature range of -60ºC to +84ºC (-76º to + 183ºF).
Connecting Cables
All Hall Effect Probes are furnished with 6 feet (1.82 meters) of connecting
cable and mating connectors for the model with which they will be used. Extension cables
are available.
Ordering Information
The Gaussmeter or Teslameter model number and the Probe type number are used as
the model number of the complete Probe. Example: A type 020 Probe for use with a Model 912
Gaussmeter would be a Model 912-020 Probe. Hall Probes for the Model 750A and 750D require
the serial number of the Gaussmeter.
