Test Equipment Description

The three axial magnetic measurement antenna RSAL 5340 corresponds to the requirements of the railway standard CLC/TS 50238-3 (Annex D) Railway applications - Compatibility between rolling stock and train detection systems - Part 3: Compatibility with axle counters. The RSAL 5340 consists of three independant, orthogonal coils, each of them equipped with a SMA-female connector. All coils have the same number of turns, the x-coil however is square-shaped whereas the y- and z-coils come with rectangular shape and larger area.
