Thanks to optical devices, Prysmian offers advanced technologies to monitor key parameters such as temperature and surrounding cable noise. Depending on the application and the used technology standard fiber optic telecom cables are suitable, while other applications may. OMRON Industrial Automation specializes in advanced automation technology, offering a range of products including photoelectric sensors and vision systems, which are essential for optical sensing applications. Distributed Fibre Optic. 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 network interfaces for. Fiber optic temperature sensors are immune to the many environmental effects that compromise other measurement technologies, can be embedded and installed in locations traditional temperature sensors cannot and deliver an unprecedented level of spatial detail and data without sacrificing precision. The distributed temperature-sensing fiber optic cable allows precise temperature measurements to be taken.
