General Inclinometers
Columbia Research Laboratories
Columbia's SI-701 Series of Inclinometers are electronic tilt sensors based on Force Balance Accelerometer technology. They produce high level low impedance output proportional to the sine of the tilt angle. Model SI-701B is a low cost general purpose sensor that can be up-graded with the addition of the Columbia "HP" torquer system (SI-701BI) for greater accuracy and ruggedness. A bi-axial version of both units (SI-702B) is also available. The Model SI-701BI is designed with an output circuit made for 4-20mA data transmission systems for industrial applications. The model SI-701FND is a fluid dampened premium performance inclinometer designed to produce accurate tilt data in extreme shock and vibration environments. The latest addition in the line is Model SI-701WPBI, a waterproof (to 150 feet) inclinometer which operates from a +15 volt supply with 4-20mA output. A single power supply powers both the sensor and the 4-20mA line driver.

Strain Sensors
Columbia Research Laboratories
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.
