Linear Variable Differential Transformer (LVDT): Definition, Construction, Principle of Operation, Advantages, Disadvantages, and Applications

LVDT is the most widely used inductive transducer that converts linear motion into electrical signals with high accuracy.
LVDT consists of a primary winding P and two secondary windings S1 and S2 wound on a cylindrical former, with a movable soft iron core inside the former.
LVDT is placed inside a stainless steel housing to provide electrostatic and electromagnetic shielding.
The differential output of LVDT is the difference between the voltages of two secondary windings, which is proportional to the displacement of the iron core.
LVDT has three cases of operation: null position, upward displacement, and downward displacement, each with a different output voltage.
The output voltage of LVDT varies linearly with the displacement of the iron core, and it indicates the amount and direction of linear motion.
LVDT has high range, no frictional losses, high input and sensitivity, low hysteresis, low power consumption, and direct conversion to electrical signals.
LVDT is sensitive to stray magnetic fields, vibrations, and temperature, which require protection and calibration.
LVDT is used in applications where displacements to be measured range from a fraction of mm to a few cms.
LVDT acts as a primary transducer that converts displacement to electrical signal directly or as a secondary transducer that converts linear displacement into an electrical signal calibrated to the readings of other primary transducers.
LVDT has various applications in aerospace, automotive, industrial, medical, and scientific fields, such as aircraft flight control, engine vibration monitoring, machine tool positioning, heart pacemaker monitoring, and seismic activity measurement.
