Macro Sensors' new digital controllers, indicators

Macro Sensors has unveiled a family of digital controllers and indicators that can be used for industrial measurement and control applications within the petrochemical, power generation, laboratory and manufacturing industries.

Offering precise measurement for applications utilizing AC- and DC-operated linear variable differential transformer (LVDT) inputs, Macro Sensors said its intelligent DMC dual channel LVDT controllers and DMI single channel LVDT indicators, offer a scrolling display that actively prompts users through set-up. The DMC controllers also offer a GUI interface, enabling operators to quickly program and view data through a computer.

Macro Sensors said both the DMC controllers and DMI indicators incorporate internal signal conditioning that provide the proper voltage for operating LVDTs and a scalable analog output to feed external instrumentation, recording or control devices. Offering readout down to 1/10,000 inch, all units provide a 0.56mm high LED front-panel digital display of measured values. DMC LVDT controllers offer six independently programmable set points with eight selectable functions, while DMI LVDT indicators offer four programmable set points with alarm status annunciator LEDs.

DMC controllers feature microprocessor-based logic and advanced software to provide digital position indication and cross-channel math functions for advanced monitoring, measuring and control, said Macro Sensors. Programmable input averaging and digital filtering allow for quick response. HI/LO limit detection is useful in a variety of "Go/No-Go" gaging applications. A standard RS-232 communications port can be used with data loggers, PLCs and computers. Units offer up to 16 excitation frequencies, selectable using the scrolling text menu in the controller setup, the company said.

"R&D staff, factory automation personnel and other technicians can easily program these controllers and indicators without engineering assistance," said Ed Herceg, Macro Sensors' N.A. sales manger. "Our digital indicators and controllers can be used on production lines to automatically gauge products for quality control and product sorting as well as in the power generation and petrochemical industries for servo position feedback on actuated equipment such as valves and dampers.

Macro Sensors said its DMC controllers and DMI indicators are priced at about one-third lower than competitive LVDT dedicated units. Units can be fitted on a panel or used as tabletop instruments. An optional network capability supports multi-channel applications by permitting the interface of multiple units within an automation system.
