The SiFlex^TM accelerometer has been designed and developed by Colibrys Inc. for “strong motion” seismic sensing applications. This MEMS capacitive product is the world best in class “digital geophone”, largely used for seismic and vibration sensing when extreme low noise measurement is required. Features such as wide dynamic range, excellent bandwidth, low distortion, high shock tolerance, and thermal stability make it ideal for applications such as earthquake and seismology measurements, homeland and border security or

structure monitoring. Used as a tilt sensor, it also provides a very high resolution of measurement.

The SF3000L is a three axis combination of SF1500S accelerometer that operates from a bipolar power supply voltage that can range from ± 6V to ± 15V with a typical current consumption of 36mA at ± 6V. The linear full acceleration range is ± 3g with a corresponding sensitivity of 1.2V/g. The frequency response over the full scale range is DC to >1000Hz for full signal as for small signal, it can raise to higher bandwidth.
