The LD400 Series miniature dc output LVDT transducers provide a method of measuring displacements up to &plu***n;5 mm (&plu***n;0.20 inch) with very high accuracy and infinite resolution. They h***e a free-guided armature incorporating Acetal bearings, which provide near frictionless motion to detect the ***allest movement the associated instrumentation is capable of identifying. These transducers utilize a precision linear variable differential transformer (LVDT) as the measuring source, together with hybrid ICs which include an oscillator, demodulator, and filter; together, they comprise a self-contained unit that accepts dc input and provides dc output relative to armature position. The unit's high linearity and low mass of moving parts is ideally suited to applicati*** in civil, mechanical, chemical and production engineering.
