Distributed fiber optic temperature sensors used to monitor underground resource temperature changes in the field mining operation "DTSX200". Will be used for the development of oil sands (containing higher mineral oil) and oil shale (containing oil). This is a production control system manufacturers for the first time to develop a fiber-optic temperature sensors used in resource development scene. Using steam, etc. when the heavy oil is extracted from oil sands, monitoring the underground temperature change is particularly important for the effective recycling of resources. The working principle of DTSX200 is extending into the optical fiber is used to monitor the well and measuring the temperature change of the oil formation containing heavy, the measured data is then used in the production control. DTSX200 applicable temperature range of -40 to +60 ° C, stable measurement even in extremely harsh environments such as deserts. Power consumption control in less than 16W, not only to ensure adequate power, but also the use of solar panels and battery-powered. In the process of the development of resources and the production control system can easily connect to improve mining efficiency. The size of the product is only about 1/4 of the previous product, the smallest in the fiber-optic temperature sensor products.
