Strain Sensors

Columbia's foil strain sensors monitor the fatigue loading experienced by tactical aircraft under various conditions of speed, weight and missions configuration. Critical undercarriage structures and control surfaces may be monitored for fatigue damage induced by high-G maneuvers and high stress landings. These sensors are self-temperatures compensating, environmental resistant, have a high output, two active arms and are easily installed. Developed for the demanding requirements associated with tactical military aircraft, they are equally useful performing many of the more common strain measurements encountered in the material testing laboratory. Columbia's foil strain sensors are considered the standard for the industry.
