Miniature
-
Columbia Research Laboratories
This group is made up of the 6000 and 7000 Series Accelerometers. The 6000 Series offers detachable cables and connector assemblies, a special inverted seismic element for mechanical isolation and other features normally available only on standard size sensors. The 7000 Series are true "shear-mode" design accelerometers which offer performance characteristics and accuracies normally only available with standard size accelerometers. High temperature models of these series are available and will operate to +500°F. For best performance use with Columbia Model 4601 Charge Amplifier or Model 5810 Inline Charge Converter.

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.

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.

Columbia Research Laboratories
Columbia Research Labs offers Angular Accelerometers that use the fluid rotor concept of sensing angular acceleration resulting in a highly accurate precision Angular Accelerometer that provide excellent bias stability and rejection of linear acceleration. We also offer smaller electrically damped Angular Accelerometers that provide exceptional high frequency characteristics for an angular acceleration within its range of sensitivity. Lastly we offer a Variable Range Angular Accelerometer allowing the customer to change the measurement range of the sensor to meet their requirements.
