Action PAK® AP6050 LVDT-Input Signal Conditioner

Provides a DC Output in Proportion to an LVDT (Linear Variable Differential Transformer) Input.

  • Displacement and Position-Sensing Applications
  • Provides LVDT Excitation Adjustable from 6-10V p-p
  • Easy Plug-In Installation/Low Mean-Time-to Repair
  • AC Line Powered
  • Three Year Warranty


The AP6050 LVDT Conditioning Module provides synchronous demodulation and conditioning for Linear Variable Differential Transformer (LVDT) transducers used in the control, display, and recording of motion.

The AP6050 LVDT Transmitter provides the AC sine wave excitation (adjustable from 6-10V p-p nominally 4kHz) for LVDT operation. The module transmits a DC voltage or current output proportional to the motion applied to the input transducer.

Zero and span are factory set, but may be field adjusted (the LVDT is assumed to be previously calibrated). Zero is adjusted for a zero output with the LVDT at its mechanical null, or zero displacement position. Span is adjusted for a full scale output with the LVDT at its appropriate mechanical extreme, or full displacement position. Zero and span are each screwdriver adjustable and accessible through the top cover of the module.

If zero and span adjustments cannot calibrate the output span appropriate to the LVDT travel input signal, roughly center zero and span adjustments and set EXC as needed to boost or decrease the LVDT's full travel signal for zero and span calibration.
