Demod-DIGITAL

Title 2

Displacement Signal Conditioner

Product Status

Introduction

LORD Sensing Linear Variable Differential Transducer (LVDT) systems enable precise micro-position measurement for a wide variety of applications. Each system includes a sensor, cable, and signal conditioning module calibrated as one unit to ensure accurate, repeatable measurement

The Demod-DIGITAL stores specific calibration values in an internal lookup table and provides a highly accurate displacement output on both digital serial and analog output channels.

NOTE: Designed for use with LORD Sensing LVDT sensors. With a Demod-DIGITAL purchase, current LORD Sensing customers may return sensors for calibration free of charge.

Product Highlights

  • Internal calibration data delivers unmatched accuracy
  • Digital serial and analog outputs
  • Up to 50X more accurate than other LORD signal conditioners
  • Clean, high-level signals to output connections

Features & Benefits
