FBG Strain Sensor with Temperature Compensation
The strain sensor makes use of the sensitivity of fiber grating to measure the strain. The FBG is fixed inside a ruggedized stainless steel housing between two anchoring points. The housing consists of a sliding mechanism that allows both ends to move freely relative to each other.

There are 2-FBG-Array inside the housing. The strain and temperature can be achieved simultaneously.

Mountable Strain Sensor MST-01

Embedded Strain Sensor EST-01
Robust and high reliability
Monitoring of compression as well as tension possible
Watertight and capable of service in harsh environment.

The strain sensor MST-01 and EST-01 can be applied to monitor strain changes in various structures for a long period of time.
