Force balance accelerometer - accelerometer SA102MFTB-SA302MFTA

Product Description:

Force Balance Accelerometer - The SA102MFTB-SA302MFTA is a precision miniature force balance accelerometer designed for use in+24 to+32 VDC aircraft power supplies. The high-level output signal and inherent self-regulation characteristics of servo loop design make these accelerometers an ideal choice for airborne telemetry applications. The output signal format is compatible with most onboard VCOs and signal processing systems. Both configurations utilize the Columbia HP torque converter system, which exhibits excellent performance and reliability in severe vibration and impact environments associated with aircraft and missile flight. The SA-302MFTA model is a compact three-axis version of the single axis SA-102MFTB model. If you need a customized version, please contact the manufacturer.

working principle:

The force balance accelerometer has a classical critical damping and second-order frequency response. There is no peak in the response, only a smooth roll off above the natural frequency. This feature, along with the excellent design of the "HP" torque generator, makes the Columbia accelerometer the best choice for high demand applications for precise DC and near DC measurements in harsh impact and broadband vibration environments. Columbia force balance accelerometers can be used for almost all applications. Low noise, high output components can be used for seismic structural motion research, while miniature, high range versions are more suitable for the more intense high-G environments encountered in many industrial, aircraft, and missile applications.

The Columbia force balanced linear accelerometer series offers low-cost, high-performance, universal single axis accelerometers that are ideal for DC and low-frequency measurements, and provide voltage and current signal outputs. In addition, solid-state sensors from Colombia and specialized onboard sensors are also available, with outputs specifically designed for+24 to+32VDC aircraft power supply, making them ideal for onboard telemetry applications. Columbia low-noise sensors are designed specifically for earthquake, low-level, and low-frequency motion research.
