Digital controllers and indicators introduced
A family of user-friendly digital controllers and indicators can be used in virtually any industrial measurement and control application within the laboratory and manufacturing industries.
LVDT controllers for measurement and control
Macro Sensors has designed intelligent micro processor based dual-channel digital controllers and indicators that can be used in a variety of industrial measurement and control applications.
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 0.0001in.
Units offer four programmable setpoints with alarm status annunciator LEDs.

Signal conditioner supports LVDT, RVDT or VRT
Macro Sensors has introduced a new single-channel DIN-rail mounted modular signal condition that supports LVDT, RVDT or half-bridge inductive sensors.
With the Series DMI Indicators, R and 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 130dB noise rejection at the excitation frequencies and is capable of 40Hz 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: * The DMI-A1 Series AC LVDT Indicator utilises 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 50Hz or 60Hz 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.
* 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.
* About Macro Sensors - Macro Sensors' extensive line of LVDT-based linear and rotary sensors are used for linear position measurement and feedback in a variety of industrial applications including factory automation, motion control systems, metal fabricating, automotive assembly as well as power plants, gas/steam turbines.
Incorporated in 1994, the Company offers more than 200 years of cumulative design and manufacturing experience by its key staff in serving its OEM and end-user international customer base.
On June 1, 2005, Macro Sensors was acquired by AST, manufacturer of state-of-the-art (Micro Electro Mechanical Structures) MEMS-based pressure sensors, transducers, and transmitters.
Common applications of AST sensor products are in industrial OEM, hydraulic systems, fuel cells, medical gases, HVAC/R, refrigeration, oil and gas exploration/production, and off-road vehicles.
