In-Situ Gasanalysator (TDLS) in Cross-Duct-Ausführung
Der In-Situ-TDLS-Gasanalysator wurde für eine Vielzahl an CEMS- und Prozessanwendungen entwickelt.
Der LAS 5000XD verwendet die durchstimmbare Diodenlaserspektroskopie (TDLS) und ist in verschiedenen Modellvarianten für die Messung von Parametern wie NH3 + H2O, HF, CO + CO2, O2, HCl + H2O, usw. erhältlich.
Der robuste Analysator mit schneller Reaktionszeit (1 s) und hochgenauer Messung, wurde für raue Umgebungen (geeignet für Ex-Zone II) entwickelt.
Die wichtigsten Vorteile des In-Situ-Laser-Gasanalysators LAS 5000XD für den Anwender sind :
- Kein Probenahmesystem erforderlich
- Kein Einfluss der Gastemperatur
- Gasmatrix frei von Interferenzen
- Kalibrierungsfreie Messung
Dank ClearPath werden Störungen durch relative Luftfeuchtigkeit, O2 oder CO2 in Spülbereichen beseitigt.
- KEY FEATURES
- New Embedded ClearPath functionality
- Highly sensitive and selective measurement
- High signal-to-noise ratio
- No measurement drift
- Response time 1 s
- Large dynamic range from ppm to %
- Real-time communication between Transmitter (Tx) and Receiver (Rx)
- Robust, ready for Ex Zone II (certification to come)
- 💡 CLEARPATH
- Interference of relative humidity, O2 or CO2 is removed in purging areas.
- Operator’s benefits:
- No need for N2 or dry air purge
- High accuracy of O2 measurement
