An LVDT is an electronic device that uses electrical and mechanical processes to convert movement along a single axis (linear displacement) into a readable signal, requiring an external power source to operate. When the ferrous core is centered at the null position, the induced magnetic flux to each of the secondary coils is equal. We know that they are electrically 180 degrees out of phase with each other, therefore, they will cancel each other, and the output voltage will be zero. As the core
