Title:
サーボ型加速度計
Document Type and Number:
Japanese Patent JP5530219
Kind Code:
B2
Abstract:
Canister-shaped magnetic reinforcing elements 31, 32 made of a ferromagnetic material having a Curie temperature higher than magnetic yokes 11, 12 are provided inside the magnetic yokes 11, 12. The inner periphery 31a, 32a of an opening in each of the magnetic reinforcing elements 31, 32 is opposed to the outer periphery 51a, 52a of each of pole piece tops 51, 52. A torquer coil 61, 62 is located between the inner periphery 31a, 32a of the opening in each of the magnetic reinforcing elements 31, 32 and the outer periphery 51a, 52a of each pole piece top 51, 52. The magnetic reinforcing elements 31, 32 provided inside the magnetic yokes 11, 12 form independent magnetic circuits. Since the magnetic reinforcing elements 31, 32 have a Curie temperature higher than the magnetic yokes 11, 12, a high accuracy of acceleration measurement in a high-temperature range can be achieved.
