Introduction SF6 sensor SF6-015 based on NDIR technology is developed for monitoring SF6 gas leakage. It is applicable for real-time online monitoring of ambient SF6 gas concentration. With high accuracy, good long-term stability, our sulfur hexafluoride sensor is widely used in fields like gas analysis industry, industrial process control, environment monitoring, power plant and transformer substation. Product Inquiry Features 1. NDIR (non-dispersive infrared) technology 2. High accuracy in full working temperature and concentration range 3. Good selectivity, no cross gas interference or poisoning 4. Fast response T90<30s (diffusion) 5. Auto baseline calibration, low drift 6. Modbus-RTU and TTL/OC digital output 7. 10+ years lifetime Specifications • Target gas: Sulfur hexafluoride (SF6) • Working principle: NDIR (non-dispersive infrared) technology • Measurement range: 0~1500ppm • Alarm point: 1000ppm (adjustable) • Response time: T90<30s (diffusion) • Resolution: 1 ppm • Accuracy: ±2%FS • Repeatability: ≤±1%FS • Data refresh time: ≤1s • Preheating time: <15s • Output: 1.
