Product Description

DTS (Distributed TemperATure Sensor) distributed multimode optical fiber temperature sensor can detect the temperature distribution of an optical fiber which is thousands of meters to dozens of kilometers long. The space sampling interval is only 1 m, and the detection period can reach second level. The fiber itself is made of quartz and has excellent electromagnetic inertia.
The distributed optical fiber temperature measurement system closely attaches the temperature measurement optical fiber to the cable, performs real-time temperature monitoring on the cable, measures the skin temperature of the cable through the temperature measurement optical fiber, and then estimates the core temperature. Temperature-measuring fiber has the advantages of continuously obtaining temperature information on the entire line of the cable, at the same time has the advantages of strong electromagnetic interference resistance, low maintenance costs, and sensitivity to temperature changes.
Fiber condition measurement and control system based on optical fiber temperature measurement technology. This system uses fiber optic temperature measurement technology to achieve temperature collection, and comprehensively analyze the food condition in combination with humidity, gas, and insect information. When abnormality is found, an alarm or linkage control ventilation equipment is implemented to achieve Real-time monitoring and regulation of granaries in real time to create suitable conditions for grain storage and achieve long-term safe and effective preservation of grain.
