  • Page 8: Brief Introduction

    Gaussmeter IGM11 Operating Instructions MAGSYS systeme Chapter 2 Brief Introduction 2 Brief Introduction Measurements with the gaussmeter utilize the Hall effect as principle of measurement. A Hall sensor is a symmetric current-carrying semiconductor. A magnetic field running perpendicular through this element generates an asymmetry on the chip and thereby creates an output voltage which, at first approximation, is proportional to the product of magnetic field strength and forced current.

    The basic network should be provided for those devices with active bus terminal. With the IGM11 the resistances of the basic network can also be mounted in the connector casing. The 5 V connection provided for the basic network at Pin 8 of the connector J4 can thus be loaded with a maximum of 50 mA.
