Description

technical field [0001] The invention relates to the technical field of displacement sensors, in particular to a piezoelectric displacement sensor for measuring vibrations. Background technique [0002] Displacement sensor, also known as linear sensor, is a linear device belonging to metal induction. The function of the sensor is to convert various measured physical quantities into electricity. In the production process, the measurement of displacement is generally divided into two types: measuring the physical size and mechanical displacement. According to the different forms of the measured variable transformation, the displacement sensor can be divided into two types: analog type and digital type, and the analog type can be divided into two types: physical type and structural type. [0003] Commonly used displacement sensors are in the majority of analog structural types, including potentiometer type displacement sensors, inductive type displacement sensors, auto-alignment...
