Noncontact displacement sensor

National Instruments’ new ECD140 sensor adds displacement and position data to test, measurement, and control systems designed around the company's CompactRIO architecture. Based on eddy-current (inductive) sensing technology, the new sensor provides displacement measurements of conductive targets with sub-micron resolutions and measurement ranges of 2mm to 3.5mm. Other ranges are also available upon request. The CompactRIO system from National Instruments is an open, expandable system powered by LabVIEW. The system allows hot swapping of a multitude of modules to quickly configure a data acquisition system. No other noncontact displacement sensor module is available for the CompactRIO system, says the company.
