The RTTR cable monitoring system consists of a temperature measurement device, the Distributed Temperature Sensing (DTS), and our visualization and RTTR calculation software, a current interface for reading in the current data, an optical fiber for temperature measurement and. The RTTR cable monitoring system consists of a temperature measurement device, the Distributed Temperature Sensing (DTS), and our visualization and RTTR calculation software, a current interface for reading in the current data, an optical fiber for temperature measurement and. Our fiber optic temperature sensing solution includes sensor, interrogator, software and data interface, as well as customizable temperature sensing probes, robust cabling with full connectorization, rack-mountable measurement devices as well as the integration of our software for read-out and. Our fiber optic sensors use a Gallium Arsenide (GaAs) crystal at the fiber tip, making them ideal for highly accurate temperature measurements in environments exposed to microwave radiation and high-frequency interference. Their fully non-metallic, dielectric design ensures complete immunity to. High-temperature measurements above 1000 °C are critical in harsh environments such as aerospace, metallurgy, fossil fuel, and power production. Fiber-optic high-temperature sensors are gradually replacing traditional electronic sensors due to their small size, resistance to electromagnetic.
