AI-TEK转速测量系统由转速传感器和转速测量仪表组成，转速传感器分主动式和被动式两种，主要采用变磁阻、磁敏电阻等测量原理，适用于各种工业、汽车等应用环境，具有防振动、防撞击等性能，在高温、潮湿和腐蚀性环境中能可靠的长期连续工作，并设计了各种高温型、高、低转速(零转速)型、防爆型等特定用途的传感器，能充分满足各种危险环境应用的需要。
转速传感器由磁敏电阻作感应元件，是新型的转速传感器。核心部件是采用磁敏电阻作为检测的元件，再经过全新的信号处理电路令噪声降低,功能更完善。通过与其它类型齿转速传感器的输出波形对比，所测到转速的误差极小以及线性特性具有很好的*性.感应对象为磁性材料或导磁材料，如磁钢、铁和电工钢等。当被测体上带有凸起（或凹陷）的磁性或导磁材料，随着被测物体转动时，传感器输出与旋转频率相关的脉冲信号，达到测速或位移检测的发讯目的。 美国AI-TEK传感器70085-1010-411安装说明： 1.
