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.

Integrated
-
Columbia Research Laboratories
Columbia's Integrated Accelerometers are completely self-contained vibration measuring systems having a built-in amplifier within the housing. Low output impedance allows operation directly into standard readout equipment without auxiliary signal conditioning. This type of accelerometer must be powered by a constant current power supply like Columbia's model 5421.

Miniature Size - AC Operation
-
Columbia Research Laboratories
The M Series of LVDT's designed by Columbia Research Labs are ideal for use on small, high-speed mechanisms and in sensitive low-displacement applications. Linear motions over the ranges of +/-0.003" to +/-0.150" are translated into precisely proportional voltage for measurement and control.

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.

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.
