测量和模拟的LVDT和RVDT传感器的输出信号。

LVDTs

线性可变差动变压器（LVDT）电力变压器传感器来测量直线位移。 LVDT的交流励磁源的驱使下，产生一对AC输出信号，根据机械位置（位移）的核心调制。常用的LVDT servomechanisms反馈位置，并自动测量机床和许多其他的工业和科学应用。

RVDTs

旋转可变差动变压器（RVDT）机电传感器传感器提供一个可变的交流电流（AC）输出电压，其输入轴角位移成正比。当固定的交流电源供电，输出信号是比指定的范围内的角位移内呈线性关系。

测量和模拟传感器的输出信号

要读取传感器的测量数据，也来测试潜在的破坏性或危险的运行限值和测试故障条件，Speedgoat支持LVDT / RVDT PCI I / O模块，包括两者的混合，测量通道和刺激输出。

LVDT / RVDT I / O模块可以被安装到“基本法”（PCI-76CL1）或经典（73LD3）实时目标机和XPC目标驱动程序库的支持。可能需要根据您的需要外部信号调理。额外的I / O模块使用可根据要求支持实时目标机的性能或自动化半长PCI外形。
