Introduction
DGM-202 operates on the principle of Hall
Effect in Semiconductors. A semiconductor carrying current
develops an electromotive force, when placed in a magnetic
field, in a direction perpendicular to the direction of both
electric current and magnetic field. The magnitude of this
e.m.f. is proportional to the field intensity if the current
is kept constant. This e.m.f. is called the Hall Voltage.
The small Hall Voltage is amplified through a high stability
amplifier so that a millivoltmeter connected at the output
of the amplifier can be calibrated directly in magnetic field
unit (gauss).
Applications
- Wide application in industry where accurate
measurements of magnetic field is required.
- Measurement of steady magnetic
- field e.g. in loud speakers, dynamo,
moving coil instruments etc.
- Useful in laboratory experiment involving
measurement of magnetic field.
- With easy interchangebility of Hall Probe,
same guassmeter can be used with both transverse and axial
probe.
