Abstract： |
The invention relates to a horizontal tunneling magneto meter, which belongs to sensor technology field. In order to solve the problem of current tunneling magneto meter that the processing difficulty is large, the invention discloses a small horizontal tunneling magneto meter for magnetic field measurement, the meter includes a head chip and feedback control circuit. The head chip is made up of silicon plate and glass. The silicon plate includes quality spring system and coil, in the quality spring system, there only has one surface is processed with coil, the Lorentz force direction generated by the current in the coil is parallel to the surface processed with coil in spring system. The merits of the invention lie in: only one surface of the sensitive element need to be processed, thus the difficulty can be decreased greatly. |
