Micron Optics, a provider of fiber optic sensing equipment, has announced the launch of the os7510 and os7520 Fabry-Perot accelerometers.
Based on Fabry-Perot (FP) technology, the os7500 is the first of its kind in sensitivity, ultra-small footprint and patented design that allows for os7500s to be deployed in series on a single optical fiber. The os7500 is also compatible, from a system level, with Fiber-Bragg-Grating-based strain and temperature sensors, thereby enabling comprehensive fiber-based sensing networks, which is important to customers monitoring civil structures as well as security applications as optical sensors are immune to EMI, corrosion, and these are inherently passive devices.
Those features, along with the fact that optical sensors require no calibration, mean no routine maintenance or annual replacement of sensors as conventional electrical gages commonly require.
The os7500 series of optical accelerometers are available in two configurations; the os7510 is optimized for long-term civil infrastructure measurements and the os7520 is designed for lower frequency range, near seismic events. These sensors can be daisy-chained on a single Hyperion channel, which allows for the sensors to be integrated into systems with strain, displacement, temperature, etc. measurements.
