Magnetic Encoder FundamentalsA magnetic encoder consists of a rotating gear made of ferrous metal and a magnetic pick-up that contains a permanent magnet and the sensing element.The gear, which is mounted on the rotating shaft, has precisely machined teeth that provide the code pattern. As the disk rotates, these teeth disturb the magnetic flux emitted …
Optical Encoder – Fundamentals The most popular type of encoder is the optical encoder, which consists of a rotating disk, a light source, and a photodetector (light sensor). The disk, which is mounted on the rotating shaft, has coded patterns of opaque and transparent sectors. As the disk rotates, these patterns interrupt the light emitted onto the …
LVDT – Linear Variable Differential TransformerLVDT is a passive transducer which measures displacement. Construction and Working of LVDT. LVDT consist of a single primary winding and two secondary wingdings.They are wound on a hollow cylindrical bobbin which is non-magnetic and insulating material.The secondary wingdings have equal number of turns and are identically placed on either …
