Page 16: Introduction
NTRODUCTION 1.1 GENERAL DESCRIPTION The Model 880A Non-Dispersive Infrared Analyzer is designed to continuously determine the concentration of a particular component of interest in a flowing gaseous mixture. Within the analyzer, two equal energy infrared beams are directed through two parallel optical cells, a flow-through sample cell and a reference cell. The Luft detector continuously measures the difference in the amount of infrared energy absorbed within each of the two cells. -
Page 17: Available Options
NTRODUCTION 1.2 AVAILABLE OPTIONS Operation of the Model 880A can be enhanced with the choice of several options: LARMS STANDARD AND FAIL SAFE User-set dual alarms are available with configurable HI/LO designations and deadband. URRENT UTPUT For normal usage, the 0/4 to 20 mA current output can be set to represent 0 to 100% of fullscale, or a suppressed range of 25% or more of fullscale may be selected. -
