Non-contact  Impedance Transducer Makes Sub-Nanometer Differential Measurements



MIDDLETOWN, CT Kaman Precision Products | Measuring presents the DIT-5200 differential impedance transducer that makes precision measurements to sub-nanometer resolution. The system also offers high thermal stability, high sensitivity, and high linearity, and senses without touching the target.


Differential systems provide greater resolution and thermal stability than single-ended systems. The DIT-5200 is a true differential system for common mode rejection yet comes without the high price of many differential systems. Based on high-precision eddy current balanced bridge technology, this system is capable of sub-nanometer resolution.


The DIT-5200 is extremely thermally stable at 0.03 % FS/C, is highly sensitive up to 10V/mil, and is extremely linear to 0.1 % full range. Kaman offers this system in single- and dual-channel configurations. The small package size of just 7.7 cubic inches leads to easy integration.


Applications for Kaman's DIT-5200 include precise alignment of fast steering mirrors, servo control position feed back, semiconductor stage positioning, angular displacement indication, X-Y orbit position feed back, and stylus position.


Kaman Precision Products | Measuring, an operating unit of Kaman Aerospace, has led the industry for over 40 years in solving difficult sensing applications when the target cannot be touched.
