FTUV Ammoniakanalysator (NH₃) (Fourier-Transformation)
Ultraschnelle Messung von NH3 (ultraschnelle Reaktionszeit: < 2 Sekunden). Die Nutzung des UV-Bereichs für die NH3-Messung wurde gezielt gewählt, um Interferenzen mit anderen wichtigen Emissionsgasen (CO, CO2, H2O usw.) zu vermeiden, die im UV nicht absorbieren.
- Very high selectivity and maximum stability thanks to the UV Fourier Transform principle
- Ultra-fast response time (< 2 sec)
- High speed DSP processor
- No risk of interferences or quenching effect due to CO, CO2 or H2O
- No internal converter, ultra-low maintenance
- High lifetime of the lamp (> 1 year of continuous use)
- Heated chamber (190°C)
- Touch screen
- Multilingual software
- Automatic compensation of pressure and temperature variations
- Engine exhaust gas monitoring
- Emission monitoring (CEMS)
- Process control (DeNOX SCR and SNCR)
