Description

The DMC-A2 Series Dual Channel AC LVDT Controller is an accurate, high performance, programmable dual channel controller that delivers precise measurement and control for applications using AC LVDT (Linear Variable Differential Transformer) inputs. The 6-digit alphanumeric LED display provides easy to follow setup prompts for all LVDT parameters using the intuitive scrolling text configuration menus.

Used in conjunction with AC LVDTs, DMC-A2 Series Controllers make up a comprehensive, reliable, measurement system. The combination can be applied to a wide variety of demanding measurement applications, such as in process gaging in automated assembly machinery, differential measurements in thickness gaging, and other comparative measurements. Utilize the controller's PLC capabilities in conjunction with the standard relays and you have an economical solution when you need control functions for comparative and direct measurements in smaller automated systems.

The DMC-A2 Series Dual Channel AC LVDT Controller is designed to be upgradeable for expansion of capabilities. You can order the controller with the standard features and if at a later time you wish to add an option like Ethernet, to add communication to data acquisition software, it can be done at the factory.

The LVDT input module of the DMC-A2 Series Dual Channel AC LVDT Controller is designed to drive and condition the signals from two AC 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 AC 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 excitation frequencies are available and are selected using the scrolling text menu in the 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 AC LVDT application setup.

If you require a single sensor. We also offer a Single Channel LVDT Indicator model number DMI-A1.
