Linear Variable Differential Transformer Sensor

We are exporter and manufacturer of Linear Variable Differential Transformer Sensor in Coimbatore, Tamil Nadu, India. Our Linear Variable Differential Transformer Sensor is a type of electrical transformer used for measuring linear displacement. The transformer has three solenoidal coils placed end-to-end around a tube. The centre coil is the primary, and the two outer coils are the secondaries. A cylindrical ferromagnetic core, attached to the object whose position is to be measured, slides along the axis of the tube. An alternating current is driven through the primary, causing a voltage to be induced in each secondary proportional to its mutual inductance with the primary. The frequency is usually in the range 1 to 10 kHz.
