Kaman Precision Products line of high precision sensors and systems provide accurate and precise non-contact position/displacement feedback in hostile environments. The inductive-based displacement sensing systems operate from -320 degrees Fahrenheit to 1,000 degrees Fahrenheit continuous and up to 1,200 degrees Fahrenheit short term. All Inconel construction makes them appropriate 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 to 77 degrees Fahrenheit or from 77 to 1,000 degrees Fahrenheit. 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 products were originally designed to measure steam turbine shaft runout in nuclear power plants. They have been used to measure nuclear fuel rod vibration, shaft vibration/runout in rocket engine liquid fuel pumps, chemical processes, research projects and high-temperature processing.
