    • Conventional ball-in-tube, gas-damped, crash sensors utilize a gold plated ball to bridge two contacts. When the ball senses acceleration (deceleration) in the longitudinal direction of a cylinder of sufficient magnitude and duration, it moves to where it bridges the contacts, completing the electrical circuit and initiating deployment of a safety restraint system. A switch activated by magnetic flux is combined with this type of gas-damped sensor to provide a solid and reliable contact duration and ensure the correct functioning of the sensor. The level of biasing force for crash zone crash sensors of this type has been increased to avoid late firing problems on marginal crashes.
    • 传统的球内管,气体阻尼,碰撞传感器利用镀金球来桥接两个触点。 当球感测到足够大小和持续时间的气缸的纵向方向上的加速度(减速度)时,它移动到桥接接触的地方,完成电路并启动安全限制系统的部署。 由磁通激活的开关与这种类型的气体阻尼传感器组合,以提供牢固和可靠的接触持续时间,并确保传感器的正确运行。 这种类型的碰撞区碰撞传感器的偏置力水平已经增加,以避免边坡碰撞造成的后期发射问题。
