The Baumer Group: Inductive Sensor with 4 nm Resolution

Oct. 13, 2012
The IPRM 12 inductive sensor offers improved measuring resolution of up to 4 nm.

This noncontact inductive sensor has been redesigned for finer resolution, making it suitable for monitoring concentricity and vibration of shafts and for highly precise measurement of manufacturing tolerances and deflections in shafts, leaf springs and levers. Since it is non-contact it will not leave scratches or pressure points on delicate finished products. The sensor features a measuring speed of 1 mm/s, and its high linearity and temperature stability allow extremely precise measurement, while the robust metal housing and protection class IP67 provide excellent durability. With all electronics integrated in its 90 mm short M12 housing, the unit is easier and less costly to integrate into compact machines than measuring systems with external evaluation units. Three versions are available: a high resolution and high linearity sensor; a high resolution, long-range sensor; and a sensor with an extended measuring range upon a minor temperature drift.
