SF6 Gas Leakage On-line Monitoring System

SF6 Gas Leakage On-line Monitoring System

Real-time monitoring • Voice prompt • Fan linkage

• Measurement range: (0 - 1500) ppm

• Maximum allowable error: ±30ppm or ±5% (display value)

• Repeatability: ≤3%

• Range and zero drift: ±3%F.S

• Response time: < 60

The SF6 gas leakage on-line monitoring system transmits the real-time measurement information of sulfur hexafluoride (SF6), oxygen (O₂) and temperature and humidity on-site to the DCS via the RS-485 bus. When the measured data exceeds the set alarm value, the monitoring system controls the activation of the audible and visual alarm or exhaust equipment. With the human infrared monitoring function, when a human body is detected, the fan will be automatically turned on. After exhausting for a certain period of time (the exhaust time can be set in the fan parameters as required), the staff can enter the work area to ensure safe production on-site.

This SF6 gas leakage on-line monitoring system is widely applicable to the power industry, metallurgical industry, petrochemical industry, etc., in places where SF6 gas is used, such as GIS electrical switches, transformers, electrical busbars, etc.

Main features

1. The SF6 gas leakage on-line monitoring system adopts an imported SF6 gas infrared sensor with an ultra-long service life.

2. Detection and display of ambient temperature, humidity and oxygen content.

3. Optional functional components such as human infrared detectors, voice prompts, audible and visual alarms, and linked fans.

4. The SF6 gas leakage on-line monitoring system supports RS-485 bus data input, and can achieve the detection, display, recording and alarm of up to 64 monitoring points.

5. Supports the remote transmission output of measurement data through RS-485.
