Kaman Precision Products offers a line of high-precision sensors and systems that it says provide accurate and precise non-contact position/displacement feedback in hostile environments. These inductive-based displacement sensing systems operate from –320°F to +1,000°F continuous and up to +1200°F short term. Its Inconel construction makes them suitable for highly corrosive gas or liquid environments, and radiation environments. Kaman’s extreme sensing systems use a dual-coil sensor design to minimize both 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°F to +77°F or from 77°F to +1000°F, according to the company. 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. All of Kaman’s 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 multiple-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.
