Linear Variable Differential Transformer LVDT Displacement Sensor

LVDT (Linear Variable Dif Ferrous Transformer) displacement sensor can be said to be a movable iron core transformer, which consists of a primary coil, two secondary coils, an iron core, a coil skeleton, a housing, and other components. When the iron core moves from the middle to both sides, the difference in output voltage between the two secondary coils is linearly related to the movement of the iron core. The measurement range is 0-5000mm; Measurement accuracy reaches 0.05%~0.5%; The linearity reaches 0.1%~0.3%; The advantages are frictionless measurement, high mechanical life, high resolution, radial insensitivity, zero position repeatability, input and output isolation, good dynamic characteristics, and the ability to work in harsh environments; The disadvantages are inconvenient to use and low linearity.
