The SiFlex^TM SF2005 accelerometer has been designed and developed by Colibrys Inc. for “strong motion” structure monitoring applications. This MEMS capacitive product is one of the best in class for seismic and vibration sensing when extreme low noise measurement is required at lower price point. Features such as wide dynamic range, excellent bandwidth, low distortion, high shock tolerance, and thermal stability make it ideal for applications such as building monitoring, industrial and process control or structure monitoring. Used as a tilt sensor, it also provides a very high resolution of measurement.

The SF2005 operates from a bipolar power supply voltage that can range from ± 6V to ± 15V with a typical current consumption of 12mA at ± 6V. The linear full acceleration range is ± 4g (± 4.5g at clip) with a corresponding sensitivity of 0.8V/g. The SF2005S and SF2005SN can operate over a wide temperature range from -40°C to +125°C and can withstand a shock of up to 1500g without performance degradation. The frequency response over the full scale range is DC to > 1000Hz for the full signal as for small signal, it can raise to higher bandwidth.
