  • Page 9: Introduction

    OptiPEAK TDL600 User Manual INTRODUCTION INTRODUCTION The OptiPEAK TDL600 Tunable Diode Laser Analyzer employs the latest techniques in laser absorption spectroscopy and signal processing power to offer a robust high performance analyzer, designed specifically for the measurement of moisture in natural gas. The analyzer is fully hazardous area certified and delivers class-leading measurement performance, stability and detection sensitivity.

  • Page 10: Theory Of Operation

    OptiPEAK TDL600 User Manual INTRODUCTION • Laser Lock System Tunable diode lasers can drift. This means that the laser wavelength may slowly change with time and, eventually, may not precisely match the absorption peak of the water. This can lead to a reduction in sensitivity and analyzer drift. This inherent property of diode lasers is overcome in the OptiPEAK TDL600 by the built-in Laser lock system.

    OptiPEAK TDL600 User Manual INTRODUCTION 1.3.1 Measurement Using a Laser The diagram below illustrates the advantages of using a laser source, compared to a traditional broadband source. The water absorption peak is shown in the center of the diagram (red area). The width of the laser beam is very narrow and is represented by the yellow line.

  • Page 13: Figure 3 System Block Schematic

    OptiPEAK TDL600 User Manual INTRODUCTION The schematic of the laser measurement system is shown in Figure 3 below. This highlights the major control and signal processing sections of the analyzer. The analyzer uses the WMS (Wavelength Modulation Spectroscopy) technique, in combination with proprietary signal processing algorithms to provide a selective response and high sensitivity to moisture.
