SF6 gas sensor

NDIRfor leak detectionmonitoring

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 and fast response, our sulfur hexafluoride sensor is widely used in fields like gas analysis industry, gas-insulated switchgear, industrial process control, power plant and high voltage transformer. 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 • 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.
