Abstract

The invention discloses a high-temperature-resistant displacement sensor probe manufacturing device and method based on a planar coil, which includes a displacement control unit, a wire feeding unit and a winding drive unit arranged on the displacement control unit, and a detachable installation with the winding drive unit. Planar coil fixed unit. The metal wire is sent into the middle of the fixed clip through the wire feeding unit and fixed on the winding shaft. The winding motor drives the winding shaft to rotate and is wound into a planar coil between the two fixed clips. The planar coil and the ceramic sheet are bonded with ceramic glue. for encapsulation. The invention has controllable cost, high reliability, and is convenient for batch production. The coil material, wire diameter, and coil size can be independently selected to manufacture suitable planar inductance coils, and the problems of making and forming non-self-adhesive planar coils are solved. The planar inductance sensor probe made of high temperature resistant materials can be used for non-contact measurement in harsh environments above 1000°C, which solves the problem of sealing processing and temperature resistance of sensor probes in extremely high temperature environments.

Description

technical field [0001] The invention belongs to the technical field of eddy current displacement measurement, and relates to a manufacturing device and method for a high-temperature-resistant displacement sensor probe based on a planar coil. Background technique [0002] The eddy current sensor is a non-contact measurement sensor with high sensitivity, large sensing range, fast response speed and simple structure. It has a wide range of application values ​​in mechanical displacement, deformation, crack detection, etc. [0003] For the measurement of small displacement of components in high-temperature equipment such as gas turbines and steam turbines, higher requirements are placed on the temperature resistance and sensitivity of sensors. In the past, the coil of the eddy current displacement sensor was made of metal copper or silver, and the maximum temperature resistance did not exceed 900°C; or the complex probe structure was used to cool the induction coil to increase ...
