The new SSI magnetostrictive displacement sensor designed based on the principle of magnetostriction has the advantages of high accuracy, long effective transmission distance, non-contact, high reliability, and adaptability to harsh environments, and is therefore widely used in various fields. At present, the purpose of displacement detection has been achieved through magnetostrictive displacement sensors composed of microcontrollers, signal excitation units, time detection units, and other units. However, displacement sensors composed of these units use a large number of circuit units, resulting in complex circuit design, high electromagnetic interference, and susceptibility to noise. The magnetostrictive displacement sensor technology based on single-chip solutions simplifies the circuit hardware, avoids electronic interference caused by excessive hardware circuits, and can achieve high-precision measurement of displacement.
