Harold G. Schaevitz LLC DC-LVDT Controller, Dual Channel (DMC-D2 Series)

Description

The DMC-D2 Series DC LVDT Controller is an accurate, high performance, programmable dual channel controller that delivers precise measurement and control for applications using DC LVDT (Linear Variable Differential Transformer) inputs. The 6-digit alphanumeric LED display provides easy to follow setup prompts for all DC LVDT parameters using the intuitive scrolling text configuration menus.

Used in conjunction with DC LVDTs, DMC-D2 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-D2 Series Dual Channel DC 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 DC LVDT input module of the DMC-D2 Series DC LVDT Indicator is designed to drive the signals for two DC 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. Scrolling text menus provide quick access to a range of configuration modes for easy DC LVDT application setup.

If you require a single sensor. We also offer a Single Channel DC LVDT Indicator model number DMI-D1.
