  • Page 17: Introduction

    1.1 OVERVIEW This manual describes the Non-Dispersive Infrared (NDIR) Analyzer Module of Rosemount Analytical's NGA 200 Series of gas analysis components. See Figure 1-1. The NDIR Analyzer Module is designed to continuously determine the concentration of oxygen in a flowing gaseous mixture. The concentration is expressed in one of three fashions: •...

  • Page 18: Theory Of Technology

    During analysis, a portion of the infrared radiation is absorbed by the component of interest in the sample. The quantity of infrared radiation that is absorbed is proportional to the component concentration. NGA Non-Dispersive Infraraed Analyzer June 1997 Rosemount Analytical 748332-D...

  • Page 20: Sample Requirements

    This change, which is proportional to component concentration, is processed and expressed as the primary variable on the network. Other modules comprising the NGA 2000 unit then use this variable for a variety of purposes (e.g., expressing the gas concentration on the Front Panel Display or sending it to external data acquisition devices).
