Pressure sensing unit for a pressure sensor

摘要

A pressure sensing unit for a pressure sensor using the magnetostriction effect of a ferrous amorphous magnetic alloy having elasticity which permits magnetostriction, and including an inductance element which has a magnetic core formed at least in part of the amorphous magnetic alloy and which is subjected to pressure so as to exert pressure on the alloy corresponding to the pressure to be measured, the resulting change in the value of the inductance being used to detect the applied pressure.
