Biaxial Inclinometers
Columbia Research Laboratories
Columbia's Biaxial Inclinometers use the same force balance accelerometer technology used in our single axis inclinometers. These Biaxial Inclinometers are used in applications where dual axis tilt measurements are required. The SI-702B series is intended for use in applications such as platform stabilization, surface mapping and measuring tilt angles in remote locations. The SI-701AI series, is designed with an output circuit configuration made for use in 4-20mA data transmission systems.

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 m...show more -

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.

General Purpose
Columbia Research Laboratories
This group of accelerometers is made up of the 3000 and 5000 Series. The 3000 Series are standard size units, including many with all welded construction, that are hermetically sealed for use in dirty and humid environments. The 5000 Series are smaller and lighter in weight than standard units. Characteristics are almost identical except that with miniature units higher natural frequencies and shock levels can be obtained due to their inherently reduced mass. Sensitivities, however are somewhat lower. High Temperature models are available that operate to +500°F. For best performance use with the Columbia Model 4601 Charge Amplifier or Model 5810 Inline Charge Converter.
