SCAIME OBAC-002 fibre-optic accelerometer

The SCAIME OBAC-002 is a fibre-optic accelerometer that offers precise and reliable low-level vibration and DC acceleration measurement. The accelerometer also has very low transverse sensitivity, which makes it suitable for motion and DC-level measurement.

The design of this miniature fibre-optics accelerometer allows flexible mounting to the testing structure, either bolted or welded. It is also highly insensitive to temperature change with thermal drift of ~0.07°C/g over the operating temperature range of -20 to 50°C. The sensor can also be directly integrated to a SCAIME web server for easy parameterisation and analysis.

This vibration sensor has application in adverse environments due to its robustness and measurement integrity, and has been used in defence and military applications and also in tankers, and the general oil and gas industry. The OBAC-002 fibre-optic accelerometer is also highly insensitive to electromagnetic interference, resistant to water and corrosive substances.

Measurement range is from -2 to 2g, with a frequency response of 0-20 Hz, transverse sensitivity of <1% and a resolution of 0.1%FS.
