Distributed temperature sensor keeps a watchful eye
The DTSX 3000 Distributed Temperature Sensor is a single device that is capable of detecting minute temperature changes, and monitoring the temperature distribution over a long distance or across a wide area. It can measure the temperature along fiber-optic cables up to 50 km in length (eight times the distance possible with the company’s previous model), with a spatial resolution of one meter. It is well suited for plant and infrastructure maintenance applications that require the monitoring of temperatures over long distances or wide areas. Specific applications include temperature monitoring of the outer walls of high-temperature industrial furnaces, the detection of gas and liquid leaks in tanks and other large production facilities, and the detection of abnormal heat levels in power lines and natural-gas-recovery processes. — Yokogawa Corp. of America, Newnan, Ga.
