Designed for detection of carbon monoxide (СО), carbon dioxide (СО2) and methane (CH4).
Application: process and working area air monitoring at NPP.
License for design of gas analysis equipment and auxiliary equipment for nuclear power stations ЦО-12-101-2359 of 07.07.2004.
License for production of gas analysis equipment and auxiliary equipment for nuclear power stations ЦО-12-101-2358 of 07.07.2004.
Principle of measurement - optical absorption.
Gas analyzer type - fixed.
Gas analyzer performs the following functions:
01. Digital indication of analyte content;
02. Generation of green-light indication upon gas analyzer energizing;
03. Generation of continuous red-light (“THRESHOLD1” and “THRESHOLD2”) and sound alarm indicating that analyte content has reached the set threshold values;
04. Commutation of external circuits with two groups of switching relay contacts (“dry contacts”) for automatic actuating device switching on (off) upon alarm “THRESHOLD1” or “THRESHOLD2” actuation;
05. Output of data on measured component concentration in a digital form via RS 232, RS 485 or current output of 4-20mA.
