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 includes a cylinder body, a piston, and a piston rod; a side wall of a cylinder body lower chamber is provided with a first radial air hole, a second radial air hole arranged on the lower end of the first radial air hole, and a third radial air hole arranged axially symmetrically with the first radial air hole; when the piston rod moves to a first position, the first radial air hole is communicated with the third radial air hole, the non-metallic position sensor send a first air pressure signal outwards; when the piston rod moves to a second position, the first radial air hole is communicated with the second radial air hole, the non-metallic position sensor send a second air pressure signal outwards.
