MIDDLETOWN, Conn., 28 July 2010. Kaman Precision Products-Measuring in Middletown, Conn., is introducing high-precision position sensors and systems for non-contact displacement and position feedback in harsh environments. All Inconel construction makes them suitable for corrosive gas, liquid, and radiation environments. Measurement quality is unaffected by most corrosive gasses and liquids and most other environmental contaminants such as oil, dirt, radiation, and stray RF and magnetic fields.
These high-temperature sensors were designed initially to measure steam turbine shaft runout in nuclear power plants. They also have been used to measure nuclear fuel rod vibration, shaft vibration/run-out in rocket engine liquid fuel pumps, chemical processes, research projects, and high-temperature processing.
These inductive-based displacement sensing systems operate from -320 to 1,000 degrees Fahrenheit continuous and temperatures as high as 1,200 F short term. Kaman's extreme sensing systems use a dual-coil sensor design to minimize thermal and radiation effects. The common mode rejection provided by the symmetrical design of the dual coils compensates for constant and slowly changing temperatures from -320 to 77 F, or from 77 to 1,000 F.
The high-temperature transducers are made with sealed, all laser-welded Inconel housings and use metal-jacketed, mineral-insulated cable. The sensors use the Kaman KDM-8200 family of signal conditioning electronics. Single- and several-channel systems are available in NEMA enclosures or bench-top/ rack-mountable Euro-format enclosures. Options are available with and without power supplies and digital displays.
