Kaman Precision Products adds displacement sensors for extreme environments



August 27, 2019 – Kaman Precision Products has anounced its line of Extreme Environment high-precision displacement sensors and systems.

With their rugged all-welded and hermetic construction, the sensors and systems are ideal for rocket and turbine engine validation testing. They can also be used for 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, specifically designed for high-pressure, low-temperature, and high-temperature conditions. The Extreme Environment sensors and systems work in operating temperatures ranging from -320°F to +1000°F (+1200°F short term). Displacement systems withstand pressures up to 5,000-pound-force per square inch (psi).

Their dual-coil sensor design effectively minimizes temperature effects. All of Kaman’s high-temperature transducers are made with hermetically sealed, all laser-welded Inconel housings and use and Inconel-jacketed, mineral-insulated cable. The sensors are unaffected by environmental contaminants and can withstand corrosive gas or liquid environments.
