characteristic TGW-919A Fiber Bragg Grating Temperature Sensing Fire Detection System
◆ Real-time online and all-weather monitoring of temperature provides important information for determining the location of the accident and the direction of fire spread. data
◆ Multi-level constant temperature alarm can be set, such as pre-alarm at 70°C, alarm at 90°C and take measures, and can be based on The environment is different and corrected. It is also possible to set multi-level differential temperature alarms, and users can customize each zone according to the actual situation. domain’s alarm temperature to provide early warning alerts
◆ The response time is short, and has nothing to do with the monitoring length and accuracy, and it can respond to temperature changes in time
◆ Adopting advanced digital measurement technology, it is not affected by factors such as light source fluctuation, connection loss, random vibration of optical cable, etc. Influence
◆ It can communicate with other external control devices through RS232/485 standard port or relay output. to network with other systems used in the fire protection field
◆ Flexible and convenient selection of probe position and density according to engineering needs
◆ Intrinsically flame-proof and explosion-proof
◆ With self-inspection function, through the self-inspection detector at the end, it can monitor its own operation in real time and output a fault alarm Sound and light signal
