Force Balance Accelerometers
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.
The Columbia product line of piezoelectric accelerometers is widely known for reliable performance, quality and ruggedness and is always expanding to meet the unique challenging and ever changing requirements of our customers. The selection of specifications, sizes and configurations is large and diverse and suitable for use on many applications requiring features such as, high performance, high accuracy, high temperature, seismic event, 4-20mA output, airborne, miniature size and general purpose use.
Columbia Research Laboratories Inc. is now the exclusive US Distributor for this line of Quartz Accelerometers. These sensors are manufactured using proven quartz flexure technology and integrated Bias and Scale Factor temperature models. These sensors are ideal for use in Inertial Navigational Systems for helicopters, manned and unmanned (UAV) aircrafts, orientation systems for oil drilling industry, Guidance systems for strategic or tactical missles, and navigation/orientation/gyrocompassing systems for naval vessels, ships, submarines, ROV, and AUV.
