Principle of Hall Effect

When placing the semiconductor carrying current in the magnetic field axial to the current direction, the semiconductor will generate transverse galvanomagnetic phenomenon, namely generate electromotive force in the direction axial to the magnetic field and current, which is Hall Effect. Hall Effect can be explained with classical galvanomagnetic theory. Generally, Hall voltage UH is expressed as:

UH=RHIB0/d= RHIIB0

Of which: d—the thickness of the Hall device

RH—Hall constant

RHI=RH/d—Constant of the Hall device

I—Current intensity passing through the Hall device

B0—The measured magnetic induction intensity

It can be seen from the formula: For a certain Hall device, the magnetic field B0 can be indirectly measured through measuring the Hall device if only the passing current I is constant. Since it can count continuously and linearly with simple method and long service life when measuring the magnetic field with Hall Effect and can measure the magnetic field of small space and small gap, Hall Effect Method has become one important method among magnetic field measurements

HGS-10C is the first hand-held type Gauss meter of HGS series Gauss meters. This instrument is the magnetic field measuring instrument specially designed for field measurement. Its design concept of lightness, practicality and portability has been determined at the beginning of instrument design and its unique design of micro power consumption allows its battery life to be greatly improved.
