Monitoring for hot spots and leaks using fiber-optic technology

Many applications have yet to be discovered

Imagine a length of ordinary telecomm grade optical fiber up to 30 km long. Envisage obtaining accurate, real-time temperature measurements along its entire length, feeding this data back to a control room (or even to your office on the other side of the world). Now imagine this optical fiber wrapped around a reactor vessel looking for hot spots, around an LNG storage tank looking for leaks or along a pipeline monitoring its integrity. This is already being accomplished with distributed temperature sensor (DTS) technology. DTS is a new temperature sensing technology that has already been proven in the field. The only limitation is the imagination.
