Abstract

The invention provides a pulsed eddy-current sensor for wall thickness detection. The pulsed eddy-current sensor comprises a box and a box cover, and the box cover is provided with a four-core aviation plug and a two-core aviation plug; an annular thin wall and a receiving coil fixing column are arranged in the box. According to the pulsed eddy-current sensor for wall thickness detection, a receiving coil can be replaced, the condition that when a technician works, traditional sensors with the different specifications need to be carried is avoided, and therefore the labor intensity is reduced; in addition, by arranging unified transmitting coils, the sensor can be fixedly connected with a convenient tool, the technician only needs to open the box cover to replace with receiving coil when the sensor is used, and therefore the fixing time is shortened; the equipment is reasonable in design, easy and convenient to operate and capable of greatly saving the working time.

Description

technical field [0001] The invention belongs to the field of sensors, in particular to a pulsed eddy current sensor used for wall thickness detection. Background technique [0002] Generally, when pulsed eddy current technology is used for wall thickness detection of pressure vessels and pressure pipelines, it is necessary to select and use sensors of different specifications according to different detection objects. On-site detection objects are complex and diverse, and it is often necessary to carry a large number of sensors of different specifications. This not only increases the cost, but also is very inconvenient to carry, and it is time-consuming and laborious to replace, so that the detection efficiency is very low. Contents of the invention [0003] In view of this, the present invention aims to propose a pulsed eddy current sensor for wall thickness detection, so as to provide a detachable combined pulsed eddy current thickness detection sensor and improve the ef...
