os7500 Accelerometer

The os7500 is a fiber optic accelerometer based on patent pending Fabry-Pérot (FP) technology. Combined with the Micron Optics HYPERION instrument platform, the os7500 offers unmatched sensitivity and multi-sensor distributed systems with other FP and FBG sensors. T

he os7500 family of sensors covers a wide range of vibration measurement applications. These sensors can be used as a replacement for conventional accelerometers, while offering the added benefits of EMI immunity, robust packaging and lightning/ corrosion resistance.

Specifically designed to address challenging environments, the os7500 family of sensors provides the user the ability to accurately measure vibrations with frequency ranges up to 350 Hz and with the highest level of sensitivity from the industry leader in optical measurement technology.

The os7500 employs a unique two-fiber I/O design that enables multiplexing of the sensors in a daisy-chain architecture. Each sensor only responds to optical signals within a 20 nm band, while passing all other wavelengths in both directions. The result allows combining up to 8 accelerometers per optical channel when used with a HYPERION instrument with a 160 nm wavelength range. The ENLIGHT Sensing Software provides a utility to calculate and then record, display, and transmit data for large networks of sensors.
