Product Introduction | FS2000 Temperature Sensing Grating Signal Processing System: One Step Ahead in Fire Warning

In tunnels, utility tunnels, petrochemical facilities, and power infrastructure, fire monitoring is challenged by complex environments, long monitoring distances, and numerous interference factors.

Traditional point-type detection offers limited coverage and fails to achieve continuous monitoring. Electromagnetic interference and flammable/explosive environments impose stricter safety requirements on equipment. Complex system integration and insufficient interface compatibility also increase deployment and maintenance costs.

The Optosky FS2000 Temperature Sensing Grating Signal Processing System is a temperature detection solution that supports long-distance continuous monitoring, featuring stability, reliability, and intrinsic safety. It enables early warning and continuous surveillance of fire hazards.

01  Fiber Bragg Grating Temperature Sensing: Stable, Reliable, and Scalable Monitoring

The FS2000 system is based on fiber Bragg grating (FBG) temperature sensing technology. It operates through a signal processing unit working in tandem with temperature sensing cables, enabling real-time and precise detection of temperature field variations.

• Zoned Alarm Technology, Flexible and Efficient Deployment

Utilizing FBG-based zoned alarm technology, fire compartments can be configured as needed. A single channel offers a wide measurement range, simplifying on-site construction and improving deployment efficiency.

• Long-Distance Transmission, Suitable for Large-Scale Monitoring

With an efficient light source design and higher output power, the system achieves long-distance signal transmission, meeting the demands of large-area, remote monitoring.

• High Reliability Assurance

Optical integration technology reduces the use of discrete optical components, effectively lowering failure risks and enhancing overall system stability and long-term operational reliability.

• Intrinsic Safety, Suitable for High-Risk Environments

Using optical fiber as the transmission and sensing medium, the system achieves electro-free detection with intrinsic safety advantages, along with excellent resistance to electromagnetic interference.

• Multiple Interfaces and Alarm Modes, Flexible Integration

Supports RS485, Ethernet, current output, and dry contact interfaces for easy system integration. Offers alarm modes including differential temperature and fixed temperature, improving the timeliness and accuracy of fire detection.
