The linear variable differential transformer (LVDT) has been widely used in applications such as power turbines, hydraulics, automation, aircraft,satellites, nuclear reactors, and many others.These transducers have low hysteresis and excellent repeatability. DC-operated LVDTs are rugged hermetically sealed sensors, constructed entirely of stainless steel 304 intended for environments with high humidity,dust and other harsh ones.
Introduction:
The linear variable differential transformer (LVDT) is a position transducer that is noncontact, absolute reading, and has essentially infinite resolution. It comprises three or more coils within which a magnetically permeable core moves to provide variable coupling between the primary coil and the secondary coils (usually two).Although the detection technique is noncontact, there is often a mechanical arrangement added to keep the core positioned in the coil throughout the stroke.
A basic LVDT comprises one primary coil,two secondary coils,and a movable core. The coils are wound onto a tubular coil form, the interior of which is called the bore(see below figure). Communication between the moving and stationary parts of the transducer is achieved by means of inductive coupling.Therefore, any number of position changes can be made without incurring wear to the transducer parts.When using an LVDT to measure the dimensions of a formed metal part (such as a fender for an automobile), the LVDT core is linked to a stylus that contacts the surface of the formed metal part. Although there may be wearing of the stylus, there is no wear of the actual sensor element.
Popular applications include industrial machinery, such as metal forming machines and in-process dimensional verification, as well as automotive and commercial products.
