Distributed Fiber Optic Linear Heat Detector

JTW-DTS-EI9017

Distributed Fiber Optic Linear Heat Detector

Характеристики

1. The main unit adopts a modular architecture design, with a minimum spatial resolution of ±0.4 meters. It supports a graphical interface, a built-in web server, and centralized management.
2. It features automated Raman optics calibration parameter calibration, a built-in calibration sensor, and one-click automatic parameter adjustment.
3. It supports various data protocols such as Modbus RTU and Modbus TCP, facilitating one-click automatic parameter adjustment for third-party backup.
4. It supports automatic fiber optic temperature calibration, curve display and polling, automatic detection of fiber optic installation quality and fiber length, zone management, and alarm display.
5. The sensor uses ordinary multimode fiber, allowing for flexible installation regardless of terrain or harsh environments, making it suitable for pipe racks, tunnels, subways, power, and petrochemical fields.
6. System composition: It consists of a main unit (signal processing unit) and detection optical cables (sensitive components), and is compatible with E18000 and E19000 series controllers to transmit temperature alarm data.
