Abstract
A tension sensor including an optical fibre having a Bragg grating is disclosed, the sensor including a housing and a support member shorter that the housing coaxially disposed therein and connected to the housing at one end. The fiber runs along the longitudinal axis of the housing and is connected to one end of the housing and to at least one location on the support member. A second Bragg grating may be provided within the support member to allow for additional measurements for temperature compensation purposes.
