Operating principle

This Gaussmeter enables user-friendly measurement of magnetic fields by applying theHall measuring principle. The Hall voltage which is generated in a Hall sensor is proportional to the adjacent magnetic field.

The attraction of the BGM 201 is the intuitive touch-screen operation and individuallyadjustable screen setups. The display on a multicolour touch-screen with backlighting can be set to Gauss, Tesla, Oersted or A/m. The corrected analogue output indicates the exact display value. Field and temperature measurements are also recorded via the probe input. Readings for all functions can be made either from the display or via software. This measuring technology is employed for example in the testing of magnetic materials in sensor technology and automotive engineering. It is integrated into continuous qualitycontrol during production and in the manufacture of DC motors.
