Overview
SF6-015 is an NDIR sensor for real-time online monitoring of ambient SF6 leaks, with high accuracy across temperature and concentration, no cross-interference or poisoning, T90 <30 s, auto-baseline calibration, Modbus-RTU and TTL/OC outputs and a 10+ year life for GIS, power plants and transformers.
Key Features
- NDIR (non-dispersive infrared) technology
- High accuracy in full working temperature and concentration range
- Good selectivity, no cross gas interference or poisoning
- Fast response T90<30s (diffusion)
- Auto baseline calibration, low drift
- Modbus-RTU and TTL/OC digital output
- 10+ years lifetime
