Intelligent Digital LVDT Controllers & Indicators Simplify Set-Up in Diverse Applications
Pennsauken, NJ, September 9, 2005...Macro Sensors, (www.macrosensors.com), an American Sensor Technologies (AST) company specializing in the manufacture of LVDT-based linear and rotary sensors, gaging probes, support electronics and related instrumentation, introduces a new family of economically-priced and user-friendly digital controllers and indicators that delivers precise measurement for applications using AC- and DC-LVDT (Linear Variable Differential Transformer) inputs.
Designed especially to optimize the use of LVDTs in automation, process or lab applications, the Series DMI Single Channel LVDT Indicators offer user-friendly set-up with a scrolling display that actively prompts users for all LVDT parameters. A 5-digit alphanumeric display, which can be calibrated in any engineering units, offers readout down to 1/10,000 inch. Units offer four programmable setpoints with alarm status annunciator LEDs. With the Series DMI Indicators, R&D staff, factory automation personnel and other technicians can easily set up and monitor the functionality of plant controllers and indicators without engineering assistance.
Designed to drive and condition the signal from an LVDT transducer, the Series DMI Single Channel LVDT Indicators contain two high-speed micro controllers and a 16-bit A/D converter that 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 application setup.
LVDT sensors used with the Series DMI Single Channel LVDT Indicators can be applied in almost all engineering applications covering civil, mechanical, petrochemical, power generation, production, aerospace, defense, and much more. They can be used on production lines to automatically gauge products for quality control and product sorting. In the power generation and petrochemical industries they can be used, for example, as servo position feedback on actuated equipment such as valves and dampers, or for measuring turbine casing expansion. Submersible units can be used in marine and offshore mining applications.
Macro Sensors offers its digital LVDT controllers in both AC- and DC-versions including:
o The DMI-A1 Series AC LVDT Indicator utilizes one of its two micro controllers to generate 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 are selectable via the scrolling text menus). Units provide a high-speed 10V scalable analog output without recalibration and built-in excitation to properly power any standard AC-LVDT.
o The DMI-DI Series DC LVDT Indicator communicates with the selected controller internally via the .2C data bus. Units offer a 10V scalable analog output without recalibration and built-in 24V DC to power virtually any DC-LVDT
Macro Sensors' Series DMI Signal Channel LVDT Indicators are economically priced at about one-third lower than competitive LVDT dedicated units. For additional information, please contact Eileen Otto at 856-662-8000/email: sales@macrosensors.com or visit our web site at www.macrosensors.com.
