Displacement Sensors | Miniature Displacement

 

The DF dc miniature displacement sensor has a friction-free core and the DFg has a free guided core incorporating Delrin bearings. All types incorporate a linear variable differential transformer (LVDT) as the measuring source together with oscillator, demodulator and fllter providing a self-contained unit accepting a DC input and providing a DC output relative to armature position.
