▎Product Introduction ：
The SF₆ Gas Leakage Online Monitoring System transmits real-time measurements of SF₆, O₂, temperature and humidity to DCS via RS-485 bus. When readings exceed preset thresholds, the system activates audible/visual alarms or exhaust equipment, while its PIR human detection automatically starts ventilation for preset durations before permitting safe worker entry - ensuring complete production safety. This system is widely applicable across power, metallurgical and petrochemical industries for all SF₆-insulated equipment including GIS switches, transformers and busbars.
▎Key Features ：
1.Long-life imported SF₆ infrared sensor.
2.Environmental temperature/humidity/O₂ monitoring.
3.Optional PIR detector/voice alerts/alarm lights/fan control.
4.RS-485 connectivity for 64 monitoring points.
5.RS-485 data transmission.
