Panametrics, ein Unternehmen von Baker Hughes, bietet Geräte auf Grundlage der abstimmbaren Diodenlaser-Absorptionsspektroskopie (TDLAS) zur Messung der Feuchtigkeitskonzentration in gängigen Gasen. Das Portfolio an TDLAS-Analysegeräten von Panametrics, zu dem auch die Aurora-Produktlinie gehört, besteht aus industriellen Analysegeräten mit intuitiven Schnittstellen und patentierter Technologie für überlegene Leistung.
Diese abstimmbaren Diodenlaser-Analysegeräte sind für ihre schnelle und genaue Reaktion bekannt und bestimmen Feuchtegehalte von 0 bis 5000 PPMv. Unser patentiertes Kalibrierungsschema berücksichtigt Schwankungen im Hintergrundgas, die bei anderen Messgeräten zu Fehlern führen würden.
Unsere TDLAS-basierten Feuchtemessgeräte benötigen keine regelmäßige Rekalibrierung und überzeugen mit niedrigen Betriebskosten.
Aurora ist in diesen drei Konfigurationen erhältlich:
- Aurora erlaubt eine sofortige Reaktion auf Prozessstörungen und ein schnelles Abtrocknen nach Gewinnung.
- Aurora TransPort bietet die Leistung eines TDLAS-Messgeräts in einem robusten, tragbaren Gehäuse, sowohl im Batterie- als auch im Netzbetrieb.
- Das Aurora Analysegerät zur Rackmontage arbeitet mit TDLAS, um den Feuchtegehalt einer Vielzahl von Hintergrundgasen genau zu bestimmen.
Our industrial TDLAS analyzer, Aurora, provides moisture measurements from 0 to 5000 PPM. Its accurate measurement technique measures moisture in many applications such as natural gas TEG dehydration, natural gas storage, transmission and custody transfer, carbon dioxide for enhanced oil recovery and carbon sequestration, metal heat-treating furnace gases, and hydrogen recycle gas in reforming. Features include:
Range
- 0 - 5000 ppm measurement range, for CO2 applications: 0 - 1000 ppm
- Dew/Frost Point: -97º to 27.3ºF (-71º to -2.6ºC) frost point @ STP of 25ºC, 14.696 psia
- Absolute Humidity: 0.095 to 237 lbs/MMSFC (1.52 to 3,803 mg/m3)
Accuracy
- ±1% of reading or ±2 ppm, whichever is greater; for > 1000 ppm, ±5% of reading
- For CO2 applications: ±3% of reading or ±5 ppmv
- For H2 recycle applications: ±1% of reading or ±2 ppmv
- Repeatability: ±0.2 ppmv or ±0.1%, whichever is greater. For CO2 applications: ±1.0 ppmv or ±0.5%, whichever is greater
- Response Time: Optical system <2 seconds
- Operating Sample Cell Pressure: 10 to 25 psia (69 to 172 kPa)
Hazardous Area Certifications
- USA/Canada: Explosion-proof for Class I, Division 1, Groups B, C, D
- EU and Elsewhere: ATEX and IECEx: Ex de IIB+H2 T6 -20°C to +65°C Flameproof with increased safety compartment
A portable industrial TDLAS analyzer, our Panametrics Aurora TransPort delivers reliability and accuracy anywhere. This on-the-go moisture analyzer rapidly responds to changes in moisture content in most gases. The unit is assembled into a rugged and transportable case with a telescoping handle and wheels.
The TransPort is ideal for spot-checking the performance of natural gas processing and drying systems, gas storage facilities, compression stations, refinery processes, heat-treating furnaces, instrument air, and more. It is ideally suited for field verification of permanently installed moisture analyzers and transmitters. Features include:
Range
- Calibrated range: 0 to 5000 ppmv. For CO2 applications: 0 to 1000 ppmv
- Lower detection level: 2 ppmv (-71.7°C). For CO2 applications: 20 ppmv (-55.3°C)
- Process dew/frost point: Process/Equivalent dew Point/Frost point calculation at user-defined constant pressure or external pressure specified by Modbus
Accuracy
- Parts per million by volume: ±1% of reading or ±2 ppmv , whichever is greater; for >1000 ppmv ±5% of reading
- For CO2 applications: ±3% of reading or ±5 ppmv. For H2 recycle applications: ±1% of reading or ±2 ppmv (for up to ±5% H2 and ±1% C2H6 variation from nominal calibration composition) (Individual instrument calibrated accuracy conditions provided in Certificate of Conformance. Accuracy of other parameters derived from ppmv.)
- Repeatability: ±0.2 ppmv or ±0.1%, whichever is greater. For CO2 applications: ±1.0 ppmv or ±0.5%, whichever is greater
- Operating sample cell pressure 10 to 25 psia (69 to 172 kPa)
Battery Life
- Rechargeable battery provides 8 to 10 hours of operation
Panametrics Aurora RM rack-mount analyzer uses tunable diode laser absorption spectroscopy (TDLAS) to accurately measure moisture in a variety of background gases. The Aurora RM analyzer is suitable for installation in safe areas and operates over a wide range of environmental conditions.
Aurora RM’s fast response immediately alerts the user when moisture concentrations are out of compliance; once corrected, gas can be quickly cleared for process normalization.
