The materials and construction techniques used in assembling an LVDT result in a rugged, durable sensor that is robust to a variety of environmental conditions. The two secondary coils are series-opposed, which means wound in series but in opposite directions. By doing so, a pressurized fluid can be contained within the tube, in which the core is free to move, while the coil assembly is unpressurized. An LVDT responds to motion of the core along the coil's axis, but is generally insensitive to cross-axis motion of the core or to its radial position. The inner coil is the primary, which is excited by an AC source as shown. Thus, by measurement of the voltage amplitude and phase, one can determine the extent of the core motion and the direction, that is, the displacement.[1] Figure 6 shows the linearity of the device within a range of core displacement. Figure 5. As shown in the figure, the DC o/p polarity or phase shift mainly defines the position of the shaft for the null point to represent the property like the o/p linearity of the module of LVDT.

The characteristics of LVDT mainly discussed in three cases like null position, highest right position & highest left position. The moving element of an LVDT is a separate tubular armature of magnetically permeable material. The signal conditioning electronics must combine information on the phase of the output with information on the magnitude of the output, so the user can know the direction the core has moved as well as how far from the electrical zero position it has moved. The LVDT is an electromechanical instrument designed to produce an AC voltage output proportional to the transformer's relative displacement and the ferromagnetic core. These same factors also give an LVDT its outstanding repeatability. To summarize, The LVDT closely models an ideal zeroth-order displacement sensor structure at low frequency, where the output is a direct and linear function of the input. It also details the requirements for measuring LVDTs, and the signal conditioning required for the measurement. Find out the active transducer. I then get an answer of 4.22 mV/V/mm.
