Siemens SIPROCESS UV600 is a specialist in extremely selective NO measurements with small measuring ranges. As an all-round device, it is also suitable for other UV-active gases such as NO2, SO2, and H2S. Thanks to its spectral range, no cross-sensitivities to CO2 and H2O are to be expected. Innovative signal processing and highly stable detectors ensure outstanding long-term stability and compensate for drift and influencing effects. With state-of-the-art electronics and software, the SIPROCESS UV600 has the necessary interfaces for remote monitoring and for connecting to process control systems.
Application
Emission measurements
- Measurement of low NO concentrations in power plants or gas tur bines
- Monitoring of NOx in denitrification plants by direct measurement of NO and NO2 as well as summation to NOx in the analyzer
- Efficient measurement in desulfurization plants
- Monitoring of very small SO2 and NO concentrations
- Emission measurements in the paper and cellulose industries
Process monitoring
- Measurement of SO2 in process gases in the paper and petrochemical industries
- Optimization of NOx emissions in exhaust gas in the automotive industry H2S measurement
- In typical emission applications
- Taking account of possible cross-sensitivities (e.g. from mercaptan)
Benefits
- Simultaneous measurement of NO and NO2 with subsequent compilation.
- NO2 converters or CLD analysers are therefore not required. This means:
- Lower maintenance effort (no converter function check)
- Reduced operating costs because no additional equipment is required, such as an ozone generator and the like
- Measurement in the UV range
- Measurement not effected by H2O and CO2
- Very low SO2 and NO measuring ranges possible
- UV Resonance Absorption Spectrometry (UVRAS)
- Measurement of very low NO concentrations: Measuring range 10 ppm
- Very low cross-sensitivity to other gases
- Very long service life of the UV light source
- Low drift and high stability through four-channel measuring method with double quotient calculation
- True reference measurement for drift-free, stable measurements
- All modules “temperature controlled,” regardless of ambient temperature fluctuations
- Optional calibration device
- Filter wheel with test cells that can be swivelled into the beam path for calibration; no test gases required
- Calibration: manual or automatic
