Differential impedance transducer makes measurements at economical price

Kaman Precision Products’ DIT-5200 differential impedance transducer makes precision measurements to sub-nanometer resolution.

Middletown, Conn., November 1, 2010—Kaman Precision Products | Measuring’s DIT-5200 differential impedance transducer makes precision measurements to sub-nanometer resolution. The system also offers high thermal stability, high sensitivity, 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 but 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 percent FS/C, is highly sensitive up to 10V/mil, and is extremely linear to 0.1 percent 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.
