The LVDT input module of the DMC-D2 Series is designed to drive and condition the signals from two LVDT transducers. The module contains two high-speed micro controllers and a 16-bit dual channel A/D converter. It communicates with the selected controller internally via the .2C data bus. One of the micro controllers generates the sine wave for the LVDT excitation frequency. These frequencies are produced as multiples of the line frequency (either 50 Hz or 60 Hz that is selectable via the scrolling text menus).

Up to 16 LVDT excitation frequencies are available and are selected using the scrolling text menu in the LVDT controller setup. The 16-bit A/D converter has over 130 dB noise rejection at the excitation frequencies and is capable of 40 Hz averaged output on 45 samples. Scrolling text menus provide quick access to a range of configuration modes for easy LVDT application setup.

The six digit, LED display can be calibrated in any engineering unit and is settable from front panel membrane switches or from the software package. All logic functions, including limit setpoint values, and auto-zero, are also set from this front control panel.

LVDT position sensors used with the DMC-A2 Series can be applied in almost all engineering applications covering civil, mechanical, petrochemical, power generation, production, aerospace, defense, and much more. They can be used on production lines to automatically gauge products for quality control and product sorting. In the power generation and petrochemical industries they can be used, for example, as servo position feedback on actuated equipment such as valves and dampers, or for measuring turbine casing expansion. Submersible units can be used in marine and offshore mining applications.
