FS61DSP: Optical Displacement Sensor for Linear Variation of Position

Based on the newLight® technology, FS61DSP Displacement Sensor is a ruggedized Fiber Bragg Grating (FBG) sensor designed to measure linear displacement on different types of structures. The sensor uses two FBGs in a push-pull configuration for effective temperature compensation.

It can be used in a large range of monitoring applications, like sustaining walls, bridge piles or buildings.

Stable

  • Effective compensation of temperature cross effect (<2micrometer/ºC) by employing two FBG
