Description
Technical field
This patent is related to stay wire sensor field, specially a kind of digital angle sensor.
Background technique
Angular displacement sensor generally comprises rotation axis and signal transmission device, and rotation axis measures angle by the rotation of itself
Circular motion is eventually converted into electric signal, but measurement range mistake by the circular motion of measurement reel by degree, signal transmission device
Small, shell adaptation size is single, preferably cannot closely fix.
Utility model content
The utility model has been designed to provide a kind of magnetic drives stay wire displacement sensor, is suitable for solving measurement range mistake
Small, shell adapts to the single problem of size.
A kind of digital angle sensor, including shell, case lid, magnet, bearing, retaining ring, mandrel, electronics integrated chip；
Described shell one end is open surface, and open surface is provided with case lid, and the mandrel is connect through shell and by bearing with shell,
Mandrel is located at enclosure interior one end and is provided with magnet, and setting live wire, electric wire one end are connected with electronics integrated chip in case lid,
Damping foil 13 is provided between electronics integrated chip 9 and magnet 5.
It advanced optimizes, the housing outer surface is provided with external screw thread, and spring washer and spiral shell are successively arranged with outside external screw thread
It is female.
It advanced optimizes, is provided with spring between the case lid and shell.
It advanced optimizes, is also arranged with retaining ring on the mandrel.
The utility model has the beneficial effects that spring is provided between case lid and shell, so that whole device is during installation
It is connected with mounting wall even closer firm；By way of Magnetic drive, water entrance can be effectively prevented, so that longer life expectancy.
