Displacement sensors target high-accuracy, high-temperature applications

By Heather Hamilton, contributing writer

Kaman Precision Products launched its Extreme Environment line of high-precision displacement sensors and systems for high-accuracy applications. They’re also suited for high-temperature applications thanks to a rugged, all-welded, and hermetic construction.

The sensors are available in three different specialized systems — high-pressure, low-temperature, and high-temperature conditions. Thanks to a dual-coil sensor design, the effects of temperature are decreased. The “Extreme Environment” sensors and systems work at temperatures of −320°F to 1,000°F (1,200°F short-term). Displacement systems can withstand pressures of up to 5,000 psi.

Kaman’s high-temperature transducers feature hermetically sealed, all-laser-welded Inconel housings and Inconel-jacketed, mineral-insulated cable, which allow the sensors to remain impervious to environmental contaminants. They can also withstand corrosive gas and liquid environments.

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

The company said that the sensors are suited for use in rocket and turbine engine validation testing, as well as other applications that depend upon high reliability, accuracy, and structural integrity. Such applications may include nuclear reactors, chemical processes, high-temperature processing, and steam and gas turbines.
