Indication and control from LVDT linear
sensors
Macro Sensors has introduced an intelligent microprocessor based dual-channel digital controller and indicator for use with LVDT-based linear sensors and gauging probes
Macro Sensors, a sensor company specialising in the manufacture of LVDT-based linear sensors and gauging probes, has designed the industry's first line of intelligent microprocessor 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, the Macro Sensors Series 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

Spring-loaded LVDTs offer consistent measurement
Macro Sensors, a manufacturer of LVDTs, RVDTs and related instrumentation, offers a line of rugged, spring-loaded AC/DC-operated LVDTs for dimensional or position measurement
R+D, factory automation and other tech staff can easily programme these controllers and indicators without engineering assistance.
The DMC Dual Channel Controllers also offers a GUI interface, enabling operators to quickly calibrate and set-up sensors, retrieve or send programmes and view and collect data remotely through a computer via RS-232 or Ethernet.
DMC Digital Controllers feature microprocessor-based logic and advanced software to provide digital position indication and cross-channel maths and control functions for advanced monitoring, measuring and control requirements.

LVDT valve position sensors for steam turbines
Macro Sensors is now a Siemens Westinghouse-approved vendor for replacement of LVDT position sensors on steam turbines, for position measurement on many types of throttle, stop and control valves
It features programmable input averaging and digital filtering and HI/LO limit detection for "Go/No-Go" gauging applications for in process gauging, quality control and product sorting.
A standard RS-232 communications port works with laptops, data loggers, PLCs and computers.
Units offer as standard, four 5 Amp 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 115-240 V 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 24VDC or 120 - 240V AC, the DMC-A2-811 Dual Channel AC-LVDT Controller provides signal conditioning for two AC-LVDTs encompassing the same operating and control features as the 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 0.56'' high LED vivid front-panel digital display of measured values.
Economically priced at about one-third lower than competitive units, the DMC Dual Channel LVDT Controllers 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.
