Julight Product – Valve Motion

LVM传感器系列（LVM=Laser Valve Motion)是专门 研发给汽车行业，非接触式地测量汽车发动机阀门运动, 包括电机马达驱动凸轮轴和产生阀门升程运动.

基本版本是配置一个或多个零延迟的激光位移传感器 高精度地实时测量阀门的位移，以及位移/速度/加速度信号输出. 零延迟功能极大地帮助了测试人员对气门升程的采集和解释,无需连续同步相对于凸轮轴曲轴编码的延迟.

An optional Laser Doppler Vibrometer based on SMI technology can be added, to allow automatic and real-time subtraction of the unwanted (but always present in practical experiments) vibrations of the engine head. The VSM system can be controlled by a PC using a dedicated software that communicates via Ethernet.
