LVDT probes or displacement sensors provide the gauge builder with the most cost effective solution for a range of dimensional precision measurement and positioning applications.
In a conventional LVDT sensor the displacement probe tip is pushed out using an internal spring. The precision bearings inside the linear displacement sensor ensure precise positioning of the gauge probe tip.
Attention to detail in both design and manufacture of the displacement sensor ensures precision measurement throughout the linear displacement transducer’s life.
PRINCIPLE & OPERATION
An LVDT (linear variable differential transformer) inductive displacement sensor is constructed using a static transformer primary winding and two secondary windings.
