Measuring device and its displacement sensor

Abstract

The application relates to the field of detection and measurement, and discloses a measuring device and a displacement sensor thereof. The displacement sensor includes: a base member, including a base part extending in the longitudinal direction and an extension part extending in the height direction from a first end of the base part; The deformation body is connected to the extension part through the connecting end and extends along the longitudinal direction adjacent to the base part at a distance, and is equipped with a contact head, and the orientation of the contact head is designed not to be in the longitudinal direction, in the When the contact head conflicts with the measuring point of the component to be measured, the elastic deformation body can swing around the connection end and relative to the base member through elastic deformation; and the displacement sensing mechanism is arranged on the Between the base part and the elastic deformation body, the displacement sensing mechanism is used to sense the displacement variation of the elastic deformation body relative to the base part. According to the technical solution of the present application, the flexible applicability of the displacement sensor is improved while satisfying high-precision measurement.

Description

technical field [0001] The present application relates to the field of measurement, and more specifically, to a displacement sensor and a measurement device including the displacement sensor. Background technique [0002] In the field of detection and measurement, displacement sensors are the core key components. LVDT displacement sensors are commonly used at present. LVDT displacement sensors can respond to the slightest movement and generate output, so they have high measurement accuracy. With the continuous improvement of the measurement operation requirements in the industry, the LVDT displacement sensor has gradually exposed its own defects. [0003] On the one hand, because the movement of the core of the LVDT displacement sensor cannot exceed the linear range of the coil, otherwise a nonlinear value will be generated, so the traditional LVDT displacement sensor is difficult to apply to the working conditions with a large range. On the other hand, due to the traditio...

Problems solved by technology

[0003] On the one hand, because the movement of the core of the LVDT displacement sensor cannot exceed the linear range of the coil, otherwise a nonlinear value will be generated, so the traditional LVDT displacement sensor is difficult to apply to the working conditions with a large range

On the other hand, due to the traditional LVDT displacement sensor, such as the written test displacement sensor, due to its own shape and size, it is often impossible to arrange it in the workplace where the measurement space is narrow (such as the narrow inner hole space), and it can only be used in the longitudinal direction or Measuring jobs are carried out in the length direction, which severely limits the choice of layout of the measuring points
