Mountable strain sensors

The mountable fiber strain sensors OSS - 531 and OSS - 532 makes use of the sensitivity of fiber grating to measure the strain. It needs external temperature sensor to compensate temperature cross-sensitivity. The signals from the sensors are processed Fiber interrogation monitors.
