• Wide Range (1G to 20KG)
  • Excellent Linearity
  • Excellent Stability
  • Interchangable Hall Probes

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).

SES-CAMM Compatible

This unit can also be connected to PC through an interface module SES-CAMM.SES-CAMM is computer aided module for connecting multiple subunits of experiments, such as Hall Effect Setup,to same interface on a computer.This feature is particulary useful in making this model compatible with computerized versions of complete experiments from our company.

Applications

  • Wide application in industry where accurate measurements of magnetic field is required.
  • Measurement of steady magnetic e.g. in loud speaker,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.
