DC Miniature - DFg Series

The DF DC/DC miniature displacement transducer has a friction-free core and 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 filter providing a self-contained unit accepting a DC input and providing a DC output relative to armature position. With high linearity and low mass of moving parts, these are ideally suited to applications in civil, mechanical, chemical and production engineering.

    Features:
  • 2, 5, 10mm measurement range
  • Infinite resolution
  • DC/DC LVDT sensor
