Inclinometer Systems
Columbia Research Laboratories
Columbia Research Labs offers our standard Inclinometer System and our Differential Inclinometer System. The standard system includes a temperature compensated force balance inclinometer in conjunction with a power module and convenient digital display. It is available with either AC or DC Power supply input. The Differential System allows the customer to match the slope of two remotely located surfaces. The readout can be set to indicate the absolute tilt of either sensor or the differential angle between them.

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.

Angular Accelerometers
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.

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.

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.
