Pressure sensors

Fiber optic pressure sensors for accurate pressure measurement in harsh environments.

 

The sensors can be used in both liquid and gaseous environments and can be easily interlinked with a variety of FBG-based sensors on a single fiber line.

 

The pressure sensor is intrinsically temperature compensated and stabilised to ensure accurate, stable and drift-free measurements over its lifetime. 

Relative pressure sensor
