Kaman Measuring Announces Extreme Environment Displacement Sensors and Systems for High Pressure, Low Temperature, and High Temperature Applications

The Measuring Division of Kaman Precision Products announced the availability of their extreme environment high-precision displacement sensors and systems. With rugged all-welded and hermetic construction, the sensors and systems are for rocket and turbine engine validation testing. They are also an excellent choice 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, 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 5000 pound-force per square inch (psi). A dual-coil sensor design minimizes temperature effects. These 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.
