Indicators take control

Macro Sensors recently introduced a new family of digital controllers and indicators that delivers precise measurement for applications using AC- and DC-LVDT (Linear Variable Differential Transformer) inputs.

Designed especially to optimise the use of LVDTs in automation, process or lab applications, the Series DMI Single Channel LVDT Indicators reportedly 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 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.
