The presented report discusses the study of LVDT and its various applications in civil engineering. LVDT is the most preferred choice for the measurement of displacement, pressure, force, level, flow, and other physical quantities in engineering applications and in industries. Measuring displacement, settlements, deformations of slopes is a critical need in many structural processes, so some sensors are used for this purpose like potentiometer, capacitance picks, LVDT etc. The main aim of studying LVDT’s is to find various other uses in structural processes advantageously which consumes less time and are more efficient. LVDT’s when used with ETPFS’s in a concrete beam can not only measure deflection of the beam but also cracks in it. LVDT has a wide range use in railways to measure dynamic displacement of rail bridges with advanced video based system. Because of its high sensitivity and high resolution LVDT’s can detect vibrations in structures. Apart from dial gauges, using a LVDT is a primitive technique for obtaining deformation in conventional structural tests. Although there are certain advantages to using LVDTs, such as high resolution and accuracy, simple installation, and real-time logging ability, there are also some disadvantages, such as high cost, the inability to obtain the whole displacement field, and extra charges for data acquisition.
