Magnetostrictive displacement sensor utilizes the principle of magnetostriction to accurately measure position by generating a strain pulse signal through the intersection of two different magnetic fields. The measurement range is 50~8000mm; Measurement accuracy less than 0.001%; Linearity less than 0.02%; The advantages are non-contact measurement, high precision, high stability, high reliability, long service life, and the ability to work in harsh environments; The disadvantage is that there must be an absolutely stable voltage input, otherwise the output will be abnormal.
