CONSTRUCTION AND CALIBRATION OF A LINEAR VARIABLE DIFFERENTIAL TRANSFORMER (LVDT)

ABSTRACT


A Linear Variable Differential Transformer (LVDT) was constructed having a primary

winding of 245 turns and two secondary windings of 100 turns each. The device
was calibrated with a graduated cylindrical rod. The graduated rod when
inserted between the hollow tube which has the windings gave output voltages of
±0.046V, ±0.51V, ±0.088V, ±0.155V, ±0.271V and ±0.395V for displacements of
±0.00cm, ±2.00cm, ±4.00cm, ±6.00cm, ±8.00cm and 10.00cm respectively. The
device when used for measurement shows that there is increase in output voltage
with increase in displacement and vice versa.
