Abstract
PURPOSE:To heighten the corrosion resistance, to prolong a life and also, to miniaturize and to lighten a weight, by forming a diaphragm by a high magnetic strain amorphous strong magnetic thin plate having a strong tenacious elasticity and detecting a propagation wave by a magnetic strain oscillation by utilizing a magnetic strain effect. CONSTITUTION:A diaphragm 1 is formed by a high magnetic strain amorphous strong magnetic thin plate having a strong tenacious elasticity and having a constitution shown by formula A and all tip ends are fixed and stuck in the window of a fluid pressure delivery pipe 4. Further, pressure due to the fluid is made to apply to the diaphragm 1 nearly vertical and magnetic strain oscillation is produced in the diaphragm 1 by an energizing element 2. Then, a propagation wave of ultrasonic wave is produced in an amorphous strong magnetic thin plate and said wave is detected by an element for detection 3. The pressure of the fluid can be detected from this characteristics of output voltage-fluid pressure because of decreasing the output voltage of the element 3 in accordance with an increase of the pressure of the fluid.
