Eddy current sensor gives higher measurement performance

Micro-Epsilon has extended its eddyNCDT 3001 series of eddy current sensors with a 2mm measuring range option, giving a resolution of 4µm.

The eddyNCDT 3001 sensor is similar in size to a typical proximity or inductive sensor, Micro-Epsilon claims its measuring performance is much greater, suiting it to OEM displacement, distance and position measurement applications. The eddyNCDT 3001 sensor is available in a compact M12 design. In addition, the sensor is said to offer high measurement accuracy and linearity, as well as a high frequency response rate of 5kHz.

The sensors are protected to IP67 and so are suitable for a wide range of applications including automation, machine building and systems integration in medium-to-high volume OEM applications.

The eddyNCDT 3001 is factory-calibrated for both ferrous and non-ferromagnetic materials, which eliminates the need for any onsite calibration. The IP67 sensor design, combined with the true eddy current measuring principle, enables measurements in harsh industrial environments as well as for offshore and marine applications. Temperature compensation range is from 0 to 70°C.
