Operating principle

Single-channel Gaussmeter with a resolution of 3 3/4 digits (4 3/4 digits) and a measuring accuracy of ± 0,20 % of the measured value. The measuring rate is 5 measurements per second (display) and 18 measurements per second with serial interface. Measurement of Hall voltage created in Hall sensor which is proportional to the adjacent magnetic field.

All the functions are displayed and controlled via the front panel of the instrument. Input via keyboard, readings on a 2-line fluorescent display with alphanumerical text. Two analogue outputs are provided. The corrected analogue output shows the exact value displayed, the non-corrected analogue output shows the field strength in real time. Field and temperature measurements are via the probe input.

The Gaussmeter 421 is used for testing magnetic materials in sensor technology and in automation. It works as an integrated component in controlling production processes and in the manufacture of DC motors.
