Low Cost Linear Variable Differential Transformer Construction and Calibration
The Low Cost Linear Variable Differential Transformer (LVDT) sensor's fabrication and calibration are discussed in this study. The iron core of the built LVDT measures 8 inches in length and 1 inch in diameter, while the probe is 4.5 inches long and 0.5 inches in diameter. By using a 1 cm known surface displacement to measure the voltage at 6.35 V, the performance of the LVDT was determined. The unknown surface waviness about voltage is measured using the constant of the known surface displacement from this. This sensor's performance accuracy ranges from 97.6% to 99.96%. When compared to other market sensors, the manufactured LVDT costs only about $28, which is little.
