    摘要: A leak-detecting sensor device (120) for a hose section (105) comprises a sensor(145a, b).The sensor (145a, b) comprises an optical fibre arranged to react to the presence of a fluid. The sensor (145a, b) is housed in a protective sleeve that is arranged for expansion and contraction when the hose section (105) expands and contracts, respectively. Tension means connects a first end of the sensor to the protective sleeve and is arranged to tension the sensor within the sleeve.
