Non-contact displacement sensor for extreme conditions
Kaman Precision Measuring Products
This company’s line of Extreme Environment high-precision displacement sensors and systems feature a rugged all-welded and hermetic construction. The sensors and systems are ideal for turbine-engine validation testing, and are also suitable for other applications that require high accuracy, high reliability and structural integrity, including nuclear reactors, steam and gas turbines, chemical processes and high-temperature processing. Three separate systems are available (photo), specifically designed for high-pressure, low-temperature and high-temperature conditions. The Extreme Environment sensors and systems work in operating temperatures ranging from –320 to 1,000°F (up to 1,200°F short term). Displacement systems withstand pressures up to 5,000 psi. Their dual-coil sensor design effectively minimizes temperature effects. — Kaman Precision Measuring Products, Middletown, Conn.
