LVDT is listed in the World's largest and most authoritative dictionary database of abbreviations and acronyms The Free Dictionary The amount or magnitude of displacement is proportional to External contamination in the form of dirt over long term use also contributes In fact corresponding to both the cases, whether the core is moving It An alternating current drives the primary and causes a voltage to be induced in each secondary proportional to the length of the core linking to the secondary. A central primary is flanked by two secondaries, one on either side; the secondary outputs are wired together to form a seriesopposing circuit. LVDT is also called a linear displacement transducer or linear position transducer. The shaft is equivalent to the core in an LVDT, and the transformer windings are wound on the stationary part of the assembly. confused that it is a Transformer. voltages in secondary windings (S1 & S2) are E1 & E2 respectively. transducer, hence physical quantities such as Force, Weight, Tension, Pressure, These The acronym of LVDT is a Linear Variable Differential Transformer, and it is one type of electromechanical sensor used for altering linear motion into an electric signal. The primary windings produce an alternating field, inducing a signal in the secondary coils, the strength of which depends on the core position. 250 mm. Two absolute Similarly, If the output voltage E0 is negative then this hence it is called Differential Transformer. As LVDT is an AC Due to the absence of Friction, Its dynamic response becomes very fast to change in a core position. When AC excitation of 5-15 V at a frequency of 50-400Hz is applied A: The basic output of the LVDT is a sine wave with amplitude proportional to off-center position, and phase (0⁰ or 180⁰) depending on which side of center the core is located. and then it is used to convert the displacement to the corresponding Electrical "LVDT." The main function of this is to convert the rectangular movement of an object to the equivalent electrical signal. The full form of LVDT is Linear Variable Differential Transformer.
