Title:
NON-METAL POSITION SENSOR FOR USE IN ELECTROMAGNETIC COMPATIBILITY TEST, AUTOMATIC ANTENNA POSITIONING DEVICE AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/118359
Kind Code:
A1
Abstract:
A non-metal position sensor for use in an electromagnetic compatibility test (01), and an automatic antenna positioning device (02) and system. The non-metal position sensor (01) comprises a cylinder (11), a piston (12), and a piston rod (13). A first radial vent (1121), a second radial vent (1122) disposed below the first radial vent (1121), and a third radial vent (1123) disposed opposite to the first radial vent (1121) about an axis, are disposed at a side wall of a lower cylinder chamber (112). When the piston rod (13) moves to a first position, the first radial vent (1121) and the third radial vent (1123) are conducted, and the non-metal position sensor (01) transmits a first pressure signal to outside the non-metal position sensor (01). When the piston rod (13) moves to a second position, the first radial vent (1121) and the second radial vent (1122) are conducted, and the non-metal position sensor (01) transmits a second pressure signal to outside the non-metal position sensor (01). Since the non-metal position sensor (01) for use in the electromagnetic compatibility test is made of a non-metal material, electromagnetic interference from testing equipment to a testing area can be minimized.
