The AC-LVDT Indicator DMI-A1 Series meter is an LVDT position sensor indicator / controller that is an accurate, programmable LVDT single channel indicator that delivers precise position measurement using LVDT sensor(Linear Variable Differential Transformer) inputs. The 5-digit alphanumeric LED display and micro-processor capability provide an easy to follow setup prompts for all LVDT parameters using the intuitive text configuration menus.

The LVDT input module of the DMI-A1 Series meter is designed to drive and condition the signal from an LVDT transducer. The mmeter contains 2 high-speed micro controllers and a 16-bit 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).

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.

AC LVDT sensors used with the DMI-A1 Series meter 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, offshore and mining applications.

If you require 2 sensor channels we also offer a dual channel LVDT Indicator Controller model number DMC-A2 Series meter.
