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。
GT系列测量传感器采用精密线性轴承来优化LVDTs的测量精度和可重复性。
在这个网站的“电子”部分中，LVDT传感器需要外部信号调节。
| 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. | |

| Air push version. |
| The air-push version of the GT displacement transducer is extended by the application of air to the displacement transducer ａnd is retracted by an internal spring. This is useful where the LVDTs position measurement tip must be retracted to allow components to move on a conveyor for example. |
