Dry type reactor fiber optic temperature measurement device-INNO

Why do reactors need to use fluorescent fiber optic temperature measurement systems

When the reactor sends abnormal or faulty signals, the faulty area of the reactor heats up and the temperature rises. By monitoring the temperature, the operating status of the reactor can be determined, thereby achieving the goal of protecting the reactor. General temperature measurement devices cannot measure the internal temperature of reactors. To solve this problem, FJINNO’s fluorescent fiber optic temperature measurement system can solve it through its anti-interference and high-temperature and high-pressure resistance characteristics.

Introduction to Fiber Optic Temperature Measurement System for Reactors

The IF-DK series reactor optical fiber temperature measurement adopts a fluorescent optical fiber temperature measurement device. The sensing probe of this device is made of non-metallic material and quartz optical fiber, which has complete electrical insulation and is not affected by high voltage and strong electromagnetic fields. It is resistant to chemical corrosion and pollution, and has fast response speed, simple installation, and high temperature resistance. The backend software is used for real-time online monitoring. The system consists of three parts: a fluorescent fiber optic temperature controller, a fluorescent fiber optic probe, and fiber optic communication software.
