Abstract

PURPOSE: To detect the size and direction of acceleration, by sealing a magnetic fluid into a large-dia. part at the center of a closed pipeline to arrange magnetic detectors at tubules extending horizontally and vertically from the large-dia. part.
CONSTITUTION: A magnetic fluid 3 is sealed into a large-dia. portion 1a at the center of a closed pipeline 1 made of a nonmagnetic material and magnet couples 4a, 4b, 5a, 5b, 6a, 6b, 7a and 7b are arranged at specified points of tubules 1bW1e extending from the large-dia. part 1a. Magnetic detectors are composed of bias magnets 8aW11a and magnetoresistance elements 8bW11b and arranged symmetrically at the specified points of the tubules 1bW1e of the closed pipeline 1. Acceleration works in the direction Xa and when an action force by the acceleration overcomes a coercive force with the magnet couples, the magnetic fluid 3 is displaced in the acceleration of Xb, opposite to the direction of the acceleration and a part thereof floss out to the tubule 1d of Xb. This enables the generation of an output voltage proportional to the working acceleration in a bridge detection circuit made up of the magnetoresistance elements.
