位移传感器

 这些传感器用于位移/位置测量。他们对位移传感器相对于位移传感器的运动(滑动部分)的运动进行了精确的测量。

该传感器采用线性变差变压器(LVDT)原理，这意味着它可能是*可靠、*可靠的位置传感器类型。LVDT传感器的原理是，传感器位置传感元件上没有电接触，传感器的用户是指清洁数据、无限分辨率和很长的生命。

我们的直流LVDT传感器具有LVDT传感器原理的所有优点，加上内置的LVDT电子设备，使直流电源和直流输出更加方便。

本系列的位移传感器可作为非制导、捕获或弹簧返回的版本。

Unguided version..
	On our unguided LVDTs the armature assembly is a separate component, to make a measurement the user must guide the armature inside the body without touching the sides. Unguided position measurement transducers are appropriate where external guidance is available ａnd give truly non-contact operation

Captive guided version..
	Our captive guided displacement transducer has bearings to guide the armature inside the measurement sensor. Captive LVDTs are for position measurement applications where guidance may be poor ａnd end bearings may be required.

Spring return version..
	Our spring displacement transducer has bearings to guide the armature inside the measurement sensor ａnd a spring which pushes the armature to the fully out position. Spring return LVDTs are appropriate where it is not possible to connect the transducer armature to the moving component being measured.
