Measurement switching device based on current vortex sensor

Abstract

The invention relates to a measurement switching device based on a current vortex sensor. The measurement switching device comprises an auxiliary measuring head, a measuring head, a housing, a measuring block, a micro-force pressing spring, the current vortex sensor and a switching nut assembly. The upper end of the housing is connected with the measuring head through a thread; the switching nut assembly is arranged in the housing; the current vortex sensor is arranged in the switching nut assembly; the measuring block made of magnetic conductive materials and the micro-force pressing spring are arranged on one side where the measuring head is arranged in the housing; one end of the micro-force pressing spring is in contact with the measuring block and the other end is in contact with the front end face of the switching nut assembly; and the measuring head is used for feeling the vibration physical quantity of a to-be-measured object and allowing the housing, the measuring block and the switching nut assembly to rotate synchronously along with the to-be-measured object during work under the action of the micro-force pressing spring, thereby allowing the current vortex sensor to feel the vibration displacement and the vibration frequency of the to-be-measured object. By use of the measurement switching device, a measuring problem of a to-be-measured body made of non magnetic conductive materials can be solved and the current vortex sensor can be used in an original occasion where the current vortex sensor cannot be used.

Description

technical field [0001] The invention relates to an eddy current sensor, in particular to a measurement adapter device of the eddy current sensor. Background technique [0002] The principle of the eddy current sensor is to accurately measure the relative position between the measured object (must be a metal conductor) and the end face of the probe through the principle of the eddy current effect. It is characterized by good long-term working reliability, high sensitivity, strong anti-interference ability, and Contact measurement, fast response, not affected by media such as oil and water, is often used for long-term real-time monitoring of parameters such as displacement, vibration, and rotational speed of various components. [0003] Generally, the measured body 13 of the eddy current sensor 11 is mostly a magnetically conductive material. When the measured body 13 is a non-magnetically conductive material, it is often necessary to perform conversion measurement through an ...
