| 摘要 |
The magnetic field measuring device uses a sensor element comprising a pivoted plate (6) supported at 2 diametrically opposite points by a carrier (1,3). The latter comprises a substrate (1) and a spacer frame (3), the pivoted plate (6) carrying a magnetisable layer with a permanent magnetistation which cooperates with the measured magnetic induction to provide a torsion movement (T) causing the plate (6) to tip. The support tags (7) for the plate (6) defining the pivot axis (8) provide a torsion force which opposes the pivoting of the plate (6) and which is measured as an indication of the magnetic field. ADVANTAGE - Simple, low-cost mfr.
