Inventor: SHOJI MASATO
IPC: G01L9/16
Filed: 1988-12-29
Abstract: PURPOSE:To improve sensitivity by setting a gap of a coil from an amorphous magnetic alloy to be 1.2mm or less. CONSTITUTION:A pressure is transmitted from a pressure introduction port 2 to a pressure chamber 3 and a stress is applied in the direction of expanding the pressure chamber 3. As the result, a form changing part 4 changes and the shape of an amorphous magnetic alloy 6 fixed on the surface of said part is changed. Due to this change in the shape, the permeability of the alloy 6 is changed by a reverse magneto-striction effect. This change is detected as a change in inductance by a pressure detecting coil 7, a differential from a differential coil 8 is read by a detecting circuit 12 and a pressure is obtained therefrom. By setting a gap of the coils 7 and 8 from the alloy 6 to be 1.2mm or less in this constitution, sensitivity can be increased.
