Kaman Precision Products, introduced position and non-contact displacement sensors made of Inconel which can resist radiation, corrosive liquid and gas environments. Sensing quality of these sensors remains impervious to environmental contaminants and caustic gases.
Position and dispalcement sensors
Initially these high-temperature designed sensors were used in nuclear power plants to measure the steam runout in turbine shafts and in rocket engine liquid fuel pumps, chemical processes, nuclear fuel rod vibration, shaft vibration, high-temperature processing and research projects.
These empirical-based displacement sensors operate on short term temperatures as high as 1,200° F and the incessant ranging from -320 to 1,000° F. Its symmetrical dual-coil design minimizes thermal and radiation effects, and the common mode rejection from these coils compensates the slow and constant changing temperatures from 77° to 1,000° F or -320° to 77° F.
The high-temperature transducers work on the Kaman KDM-8200 family’s signal conditioning electronics and use metal-jackets and mineral-insulated cable, sealed and laser welded with Inconel. NEMA and Euro-format enclosures provide information on the channel systems with and without digital displays and power supplies.
