Yokogawa to release DTSX 3000 distributed temperature sensor

Hydrocarbon Engineering,

Yokogawa Electric Corporation has announced that it will release the DTSX®3000 distributed temperature sensor on 12 August 2014.

The sensor has a one metre spatial resolution, and is capable of measuring the temperature along fiber-optic cables up to 50 km in length, eight times the distance possible with the previous model.

According to Yokogawa, the DTSX3000 is well suited for plant and infrastructure maintenance applications that necessitate the monitoring of temperature over long distances or across wide areas. Specific applications include the detection of gas and liquid leaks in tanks and other large production facilities, and the detection of abnormal heat levels in power lines.

The development of shale gas fields requires sensors that are capable of detecting even minute changes in the temperature distribution in a bedrock formation during hydraulic fracturing process. The DTSX300 is capable of measuring the distributed temperature along a 6 km fiber-optic cable, with a top-level temperature resolution of 0.03 °C, 20 times the precision possible with conventional product.

An earlier model

Yokogawa currently sells the DTSX®200 distributed temperature sensor for use in applications that include the monitoring of temperatures in unconventional oil and gas wells, the detection of leaks of high or low temperature liquids and gasses from pipelines or tanks, and the detection of abnormal heat buildup in coal and wood chip conveyors.

In contrast to conventional techniques that rely on the use of multiple surveillance cameras or thermocouples and resistance temperature detectors, distributed temperature sensors can be easily routed along the course of any object that requires management. Temperature readings can be displayed on a computer monitor, allowing maintenance personnel to quickly spot and respond to any problems.
