LVDTs
LVDT (Linear Variable Differential Transformer) is an absolute position transducer/displacement transducer that converts a linear position or 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 sensor operation does not require an electrical contact between the moving part (probe or core assembly) and the coil assembly, but instead relies on electromagnetic technology; this and the fact that LVDTs can operate without any built-in electronic circuitry are the primary reasons why these products have been widely used in applications where long life and reliable equipment is required under very severe environmental conditions, such as in Military/Aerospace, process controls, automation, robotics, nuclear, chemical plants, hydraulics, power turbines, and many other systems. LVDTs come in two different ranges, either DC or AC output. DC versions, in general, have integral electronics or there is limited need for complex signal conditioning, while AC variants will require signal conditioning. There are many application-based uses for an LVDT product, as they are not electromechanical, making them suitable for a wide variety of motion measurement tasks. LVDTs are available in multiple series to suit different industrial applications, and some models include built-in switches for enhanced control.
