베이커휴즈 Panametrics는 가스 혼합물의 농도를 측정하는 파장 가변형 다이오드 레이저 흡수 분광법(TDLAS) 솔루션 포트폴리오를 제공합니다. Aurora 제품 라인으로, 직관적인 인터페이스를 지원하며 구성 및 작동이 용이한 최첨단 습도계로 구성되어 있습니다.
특히 파장 가변형 다이오드 레이저는(TDL) 뛰어난 응답 속도 및 정확성을 자랑하며 이를 통해 매우 낮은 PPM부터 퍼센트 수준까지의 수분 측정 분석이 가능합니다. 고온, 저온, 다습한 환경 등 혹독한 환경에서도 안정적으로 작동할 수 있도록 엄격한 테스트 과정을 통해 검증되었습니다.
또한 TDLAS 습도계는 재교정이 필요 없으며 소유비용이 낮아 경제적입니다.
Aurora 제품 라인은 다음과 같은 트랜스미터를 제공하고 있습니다:
- Aurora 수분 분석기: 공정이 어긋나거나 수분 농도가 공정 사양에 적합하지 않을 경우 사용자에게 이를 즉각적으로 알립니다
- Aurora TransPort 수분 분석기: 이동 중에도 측정과 현장 검사를 수행할 수 있도록 휴대용으로 설계되었습니다
- Aurora 19 수분 분석기: 금속 열처리 용광로 가스, 산업용 및 불활성 가스, 글러브 박스, 압축 공기, 테스트 및 교정, 흡착식(Desiccant) 드라이어/멤브레인(Membrane) 드라이어 테스트 및 모니터링 등 다양한 적용 분야를 대상으로 매우 낮은 PPM 수준의 정밀한 측정을 제공합니다
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

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.
