Functional Diagram Of Lvdt. Ad598 functional block diagram an external sine wave reference source two secondary windings connected in series and the moveable core to couple flux be tween the primary and secondary windings. The ad598 energizes the lvdt primary senses the lvdt secondary output voltages and produces a dc output voltage proportional to core position.
Linear displacement is the movement of an object in one direction along a single axis. There are a total of two secondary coils which are always wounded on the top of the primary coil. The primary coil of linear variable differential transformers winding is wound on the entire length of non ferromagnetic liner or bobbin which is typically made of some ceramic or plastic material.
The ad598 energizes the lvdt primary senses the lvdt secondary output voltages and produces a dc output voltage proportional to core position.
The main function of this is to convert the rectangular movement of an object to the equivalent electrical signal. The lvdt transformer consists of a single primary winding p1 and two secondary windings s1 and s2 wound on a cylindrical former. Linear displacement is the movement of an object in one direction along a single axis. The linear variable differential transformer lvdt also called linear variable displacement transformer linear variable displacement transducer or simply differential transformer is a type of electrical transformer used for measuring linear displacement position.
