Series 500

All Positive DC-DC LVDTs

The Series 0500 DC-DC LVDTs are designed with an internal 3kHz oscillator and a demodulated output (available in 0-5VDC or 0-10VDC). The transducer has reverse polarity protection, shares a common ground and can be operated with a 13.5-20VDC input voltage. Designed with an offset stroke, the core can travel in an all-positive direction ranging from 0-0.25” to 0-20”. As the core is displaced axially, the demodulated output will be directly proportional to the displacement. With an all-positive output, this LVDT is perfect for data acquisition.

Key Features

  • Ranges from 0-0.25” to 0-20”
  • Convenient DC-DC operation
  • Non-linearity ≤ ±0.25%
  • Input VDC Excitation ranges 13.5-20V

*All models are fed input VDC and can be configured to output either 0-5VDC or 0-10VDC. The blank “_” digit in the model number will be either:

  • 1 for 0-5VDC output
  • 2 for 0-10VDC output

NOTE: CIRCUITRY WITHIN THE UNIT MAY CAUSE LEAD-END HOUSING TO BE WARM TO THE TOUCH.

REVERSE DISPLACEMENT

The 0500 Series can be configured for reverse displacement; output starting from the lead-end of the transducer. The 050_-_0010 units are otherwise identical to their standard non lead-end output counterpart both electrically and mechanically.

The recommended core extension rods are made of nonmagnetic stainless steel and are sized to allow the transducers to operate over their full range. Extension rods from models with longer strokes may be used to facilitate installation. Using extension rods shorter than recommended may reduce the LVDTs usable measurement range.
