when do you obtain null position in lvdt
Linear variable differential transformer The LVDT converts a position or linear displacement from a mechanical reference (zero, or null position) into a proportional electrical signal containing phase (for direction) and amplitude (for distance) information. The LVDT operation does not require an electrical contact between the moving part (probe or core assembly) and the coil assembly, but instead relies on electromagnetic coupling.
Colony of Virginia The Colony of Virginia, chartered in 1606 and settled in 1607, was the first enduring English colony in North America, following failed proprietary attempts at settlement on Newfoundland by Sir Humphrey Gilbert[2] in 1583, and the subsequent further south Roanoke Island (modern eastern North Carolina) by Sir Walter Raleigh in the late 1580s.
