This sensor consists of mercury as electric-conductive liquid, permanent magnet, Y-shape liquid passage, electrodes detecting liquid velocity, multi-hollow fibres as a G'level setting method, non-return ball valve, electronic voltage amplifier, comparator, and thyrister switches. This sensor shows short-time crash discrimination and high reliability.
