The SiFlexTM 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 strong motion 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 for precise measurements.
In order to provide an ideal support to our customers, our standard SF1500S and SF1500SN products are available worldwide through a wide network of distributors and agents or directly at Colibrys. Do not hesitate to access our "contact/ sales & support network" web page for precise contacts or directly Colibrys in Europe or in the US for more details.

The SF1500 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 ± 3g with a corresponding sensitivity of 1.2V/g.
The SF1500S.A and SF1500SN.A 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 > 1500Hz for full signal as for a small signal, it can raise to 5000Hz.
