The DTSS is the most advanced optical fiber distributed strain sensor available on the market today. Packaged in a 19" rack mountable chassis with an optional high-resolution monitor and keyboard, the DTSS offers a truly mobile strain measurement solution, additionally capable of temperature measurements and dynamic strain measurements. DTSS is capable of measuring strain and temperature distributions along optical fibers up to 10km in length with a strain resolution of ±10µε at 1m intervals and a temperature resolution of ±0.5ºC at 1m intervals. The DTSS is suitable for various applications from oil well monitoring to dam surveillance and structural monitoring. The DTSS is unique in being able to measure both strain and temperature both simultaneously and independently. It is uniquely able to measure fully distributed strain at dynamic acquisition rates of up to 10Hz, allowing monitoring of dynamic applications such as flexible oil risers or train track monitoring.
