L.V.D.T Products
-
Columbia Research Laboratories
Columbia's L.V.D.T.'s are designed for the most demanding high temperature military and industrial applications where maximum life under adverse conditions is required. The corrosion resistant stainless steel housing provides effective shielding to contain the magnetic flux within the transformer, as well as providing protection against external magnetic fields. Conservative design permits the use of these transducers well beyond their specific linear range with minimum loss of accuracy.

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.

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.

Accelerometers
-
Columbia Research Laboratories
The force balance accelerometer has a classical critically-damped, second-order frequency response. There is no peaking in the response but simply a smooth roll-off above the natural frequency. This property along with the excellent characteristics of the "HP" torquer design makes Columbia accelerometers the best choice for demanding applications where precise DC and near-DC measurements are needed in demanding shock and wide band vibration environments. Columbia force balance accelerometers are available to cover virtually all applications. Low noise, high output units can be used for seismic structure motion studies while miniature, high range versions are optimum for measuring more violent high G environments encountered in many industrial, aircraft and missile applications.
