Sensors & Systems Take On The Highs And Lows

The Measuring Division of Kaman Precision Products offers a line of extreme environment high-precision displacement sensors and systems featuring rugged all-welded and hermetic construction. The sensors and systems are said to be ideal for rocket and turbine engine validation testing and other applications demanding applications including nuclear reactors, steam and gas turbines, chemical processes, and high temperature processing.


Three separate systems are available 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). A dual-coil sensor design effectively minimizes temperature effects.


All 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.


The KD-1925, KD-1950 and KD-1975 Extreme Environment displacement sensors use KDM-8206EE signal conditioning electronics. Available are a full variable channeled rack with up to 12 channels, a half rack system with up to 6 channels, and the NEMA housing enclosure.
