For a kind of disassembled assembled pulse vortex thickness detecting sensor, the efficiency of Site Detection is improved.
To reach above-mentioned purpose, what the technical solution of the utility model was realized in：
A kind of impulse eddy current wall thickness scanning sensor installs housing, including box body and lid, annular is provided with box body thin
Wall and receiving coil fixed column；Lid is provided with four core aviation plugs and two core aviation plugs.
Further, the box body is hinged with lid.
Further, the lid is provided with a buckle, and box body is provided with the groove corresponding with the buckle.
Further, described annular thin wall one end is provided with inverted L-shaped breach.
Further, it is arranged with receiving coil bobbin winoler in the receiving coil fixed column.
Further, the annular thin wall is sheathed on receiving coil fixed column periphery, annular thin wall and box body medial surface it
Between be provided with transmitting coil space, receiving coil bobbin winoler is provided between annular thin wall and receiving coil fixed column.
Relative to prior art, a kind of impulse eddy current wall thickness described in the utility model scanning sensor is installed housing and is had
There is following advantage：
A kind of impulse eddy current wall thickness described in the utility model scanning installs housing with sensor, can change reception line
Circle, it is to avoid technical staff when carrying out doing industry, because of different detection targets the need for, it is necessary to carry the tradition sensing of different size
Device (transmitting, reception integrative sensor), alleviates carrying weight；And the setting of unified transmitting coil so that sensor with
The connection of portable tool can be fixed, and need to only open the lid replacing receiving coil when using, and compared with traditional sensors, subtract
The set time of sensor is lacked；The equipment is reasonable in design, easy to operate, substantially increases pressure vessel and pressure pipeline wall thickness
The efficiency of detection.
