Presentation Transcript

  1. LVDT & RVDT End of World War II

  2. Linear Variable Differential Transformer(LVDT)

  3. PRECISION ABSOLUTE VALUE CIRCUIT(FULL-WAVE RECTIFIER)

  4. LVDT & RVDT Comparison LVDT • Measurement ranges are ±100µm to ±25cm • Sensitivity is 2.4mvper volt per degree of rotation • Input voltages are from 1V to 24V RMS, with frequencies 50Hz-0kHz RVDT • Typical RVDTs are linear over a range of about ±40º • Sensitivity is 2 to 3mV per volt per degree of rotation • Input voltages in the range of 3V RMS at frequencies between 400Hz and 20kHz.

  5. Advantages LVDT • Infinite Resolution • High accuracy and sensitivity • Excellent linearity ( 0.5%) • A wide variety of measurement ranges

  6. Application • Modern Machine-tool • Robotics • Avionics & aircraft • Process control industry • Torpedo, and weapons systems.
