Macro Sensors DMC dual-channel LVDT controllers offer simplified sensor calibration and set-up with a scrolling display that actively guides users on what information to input.

Macro Sensors has designed the industry's first line of intelligent micro processor based dual-channel digital controllers and indicators that can be used in a variety of industrial measurement and control applications within the petrochemical, power generation, laboratory and manufacturing industries.

Offering precise measurement for applications utilising ac and dc operated LVDT (Linear Variable Differential Transformer) inputs, Macro Sensors DMC dual-channel LVDT controllers offer simplified sensor calibration and set-up with a scrolling display that actively guides users on what information to input.

RandD, factory automation and other tech staff can easily program these controllers and indicators without engineering assistance.

The controllers also offers a GUI interface, enabling operators to quickly calibrate and set up sensors, retrieve or send programs and view and collect data remotely through a computer via RS-232 or Ethernet.

They feature microprocessor-based logic and advanced software to provide digital position indication and cross-channel math and control functions for advanced monitoring, measuring and control requirements.

They offer programmable input averaging and digital filtering and hi/lo limit detection for "go/no-go" gaging applications for in process gaging, quality control and product sorting.

A standard RS-232 communications port works with laptops, data loggers, PLCs and computers.

Units offer as standard, four 5A Form A relays that are selectable using the scrolling text menus or the in controller software interface.

Macro Sensors offers its digital controllers and indicators in both ac and dc versions.

The DMC-D2-811 dual-channel dc-LVDT controller scrolling meter operates from 115-240V AC or 18-24V DC and provides proper voltage for operating any standard DC-LVDT.

Its dc LVDT input module is designed to drive the signals for two DC-LVDT transducers.

Powered from 24V dc or 120 - 240V AC, the DMC-A2-811provides signal conditioning for two ac-LVDTs encompassing the same operating and control features as its dc counterpart.

Both DMC Controllers incorporate provisions that supply the proper voltage for operating LVDTs and a scalable analogue output to feed external instrumentation, recording or control devices.

DMC dual-channel LVDT Controllers have six independently programmable set points with eight selectable functions.

Offering a six-digit readout, units provide a bright LED vivid front-panel digital display of measured values.

The units can be fitted on a testing station panel, control cabinets or OEM equipment.

An optional Ethernet network capability supports multi-channel applications by permitting the interface of multiple units within an automation system.
