Abstract

In this report we will present some preliminary results on a RF sub-carrier based fibre strain sensing system for on-line monitoring of composite high pressure storage tanks for natural gas or hydrogen. By employing a temperature compensation scheme to the system developed has shown stable performance with better than 20μm length resolution and comparable long-term drift. The system uses readily available components and could be used for low-cost high volume applications such as on-line continuous monitoring.
