Accelerometer SA107AIC - Force Balance Accelerometer SA107AIHPC Product Description:

The design of the SA107AIC force balance accelerometer SA107AIHPC has an output circuit configuration and can be used for 4-20mA data transmission systems. The 4-20 mA system is widely used in industrial installations for long-distance data transmission in environments that may cause interference with nearby power lines. A single+15V power supply supplies power to sensors and 4-20mA line drivers. The SA-107AIC model is a low-cost device, while the SA-107AIHPC adopts the HP torque generator design patented by Colombia, which can improve accuracy and repeatability in adverse impact environments. Both configurations provide convenient 6-pin electrical interfaces. The SA-107BIC and SA-107BIHPC accelerometers have similar configurations, providing not only current output but also voltage output. 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.
