Columbia manufactures a wide range of sensors and associated signal conditioning electronics that can be used in a variety of applications. Our product line includes force balance inertial-grade accelerometers and inclinometers, piezoelectric vibration and pressure sensors, strain gage aircraft mainframe fatigue sensors, precision linear variable differential transducers, and fiber optic sensors. Columbia sensors have been installed in military aircraft, in-flight missile systems, and/or interplanetary manned and unmanned space vehicles. Our sensors are used extensively in industrial control and monitoring systems. Columbia also supplies operational sensors used to measure vibration, acceleration, temperature, and strain for a host of applications.
Airborne / Flight Qualified Sensors
Airborne Accelerometers are designed to operate from a single power supply of +24 to +32VDC, typical aircraft power supply. They are also designed with a high degree of power supply regulation in order to isolate the output from power supply variations experienced in the aircraft. Columbia Research Labs offers three accelerometers that were specifically designed to run from this aircraft power.
The single axis SA-102BHC and triaxial SA-302BHC are premium performance force balance accelerometers. Their rugged construction makes them well suited for demanding missile and airborne applications. The basic systems have been qualified and supplied in substantial volume on many small missile programs. These designs have also been selected by a number of aircraft instrument manufactures as key components of their strap?down systems. The miniature single axis SA-102MFTB is an excellent candidate for airborne telemetry applications. The output signal format is compatible with most airborne VCO's and signal processing systems. All three of these models incorporate the Columbia HP torquer system, which provides exceptional performance an reliability in severe vibration and shock environments associated with aircraft and missile flights.
In addition to accelerometers Columbia Research Labs manufactures a flight qualified fatigue monitor strain sensor. Series DTD2684 was developed for the demanding requirements associated with tactical military aircraft. They provide an accurate representation of the fatigue loading experienced by tactical aircraft under various conditions of speed, weight and mission configuration. Critical areas, such as under carriage structures and control surfaces may be more accurately monitored for potential fatigue damage induced by high-g maneuvers and high stress landings.
