  7. System signal layout

  8. TDL technique

  9. TUNING THE LASER Δλ ΔT NIR semiconductor laser Controlled variations in temperature will ”tune” the diode lasers output wavelength. The temperature variations are created by applying a sinus shaped drive current with a frequency of 1 kHz, with a temperature accuracy of 0.001 C˚

  10. ABSORPTION SPECTRUM Laser is tuned around one or a few absorbtion lines, Scanned range is typically less than 1 nm Absorbance 100% O2 HF H2O 0 % 1.35 um 1.25 um

  11. SPECTRA HANDLING ”Zero” signal ”Measurement” signal Resulting spectrum The scanned spectra are resolved into 1000 channels Measurement spectrum is divided with the Zero spectrumto obtain the resulting spectrum and to eliminate noise generated by the laser

  12. EVALUATION The cross section area of the obtained spectrum is used to calculate the concentration by use of Beer Lamberts law, compensated for line widening effects I1 I2 Ln ( I1 / I2 ) x l C = α1 – α2 + Line Widening effects due to temperature & partial pressure

  13. MEASURING TEMPERATURE Absorption lines Temperature can be measured by studying the proportions and relations of the absorption lines, as they change with temperature

  14. PERFORMANCE

  15. Options • Additional laser heads (up to 4) • Additional monitoring paths (up to 4) • Additional serial ports • Additional communication card CC202L • RE060L-EEx receiver for use with EM060L emitter for explosion classed areas Zone 1 • External screen

  16. Accessories • AC180 Air-conditioned cabinet • Auto-calibration equipment • MX10XL Multiplexer* • MXX01L Demultiplexer* • I/O Management software IO256 • Digital and analogue input and output modules • Short-haul modems • Sensors • Dataloggers • EnviMan Software

  26. ANALYZER ROOT MENU [F1] Installation - 분석기의 모든 설정을 입력 또는 수정할 수 있다. [F2] Data presentation – 분석기의 History를 보여준다. [F3] Calibration - 이것은 분석기의 calibration을 초기화또는 수행하기 위한 메뉴이다. [F4] Measurements - 측정 mode를 활성화한다. [F5] System check - 분석기의 상태를 체크한다.

  27. System Check

  28. LA 060 Alignment 뿐만 아니라 광케이블의 단선 및 광량 Check함에 있어 유용하게 사용된다. It’s maintenance tool

  29. Alignment 1. Alignment를 실시할 때 분석기는 항상 optimize light menu로 변경해야만 한다. 2. 발광부에 LA060 Kit를 연결하여 레이저를 조사하면서 수광부측에서 육안으로 강한 레이저를 확인할 수 있다. 3. 만약 레이저가 육안으로 확인되지 않을 경우, 발광부의 Alignment 나사를 조정해 레이저를 수광부와정렬할 수 있다. 4. 수광부 측에 강한 빛이 들올 때, LA060 kit를 제거한 후 분석기광케이블을 연결한다. * Mux panel의 RC101L 또는 Light Level을 분석기 상태를 먼저 확인한 후 발, 수광부의 Alignment 나사를 미세조정하여 Light Level 최소25% - 최대40%로 유지한다. * Alignment 특성상 2인 1조로 실시하여야 한다.

  30. ANALYZER INSTALLATION MENU [F1] Station setup - 분석기의 시간, 날짜, 패스워드 및 프린터 설정을 위해 사용된다. [F2] Measurement Setup -측정에 대한 사양 설정을 위해 사용된다. [F3] Calibration Setup - 가스 실린더, calibration paths, 그리고 calibration 실행절차를 정의하기 위하여 활성화된다. [F4] Communication Setup - 모뎀 사용자를 위한 메뉴이다. [F5] Input signal Setup - Io256 프로그램을 Load 한다. [F6] output signal Setup - Output 설정을 위한 메뉴이다. [F7] Emulator Setup - 분석기가 Odessa logger에 연결되어 있을 때, DSM 에뮬레이터는 통신을 가능하게 만들기 위하여 필요하다. [F8] Optimize light – Alignment 시 최대의 light intensity를 얻기 위하여 발,수광부 조정 시 사용한다.
