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 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
