NON-METALLIC POSITION SENSOR FOR ELECTROMAGNETIC COMPATIBILITY TEST, DEVICE AND SYSTEM FOR AUTOMATIC ANTENNA POSITIONING

摘要

Provided are a non-metallic position sensor for electromagnetic compatibility testing, a device and a system for automatic antenna positioning. The non-metallic position sensor comprises a cylinder body, a piston and a piston rod; a side wall of a lower cylinder body chamber is provided with a first radial air hole, a second radial air hole disposed at the lower end of the first radial air hole, and a third radial air hole axially disposed axially of the first radial air hole; when the piston rod moves to a first position, the first radial air hole communicates with the third radial air hole, the non-metallic position sensor sends out a first air pressure signal to the outside; When the piston rod moves to a second position, the first radial air hole communicates with the second radial air hole, and the non-metallic position sensor sends out a second air pressure signal to the outside. The non-metallic electromagnetic compatibility testing position sensor provided by the present disclosure is a wholly non-metallic material so that electromagnetic interference caused by a test device on the test area is maximally avoided.
