61-1004RK/61-0191RK Carbon Di oxide Detector

Overview

This manual describes the 61-1004RK CO2 (carbon dioxide) detector. This manual also
describes how to install, start up, maintain, and calibrate the detector when used with a

gas monitoring controller. A parts list at the end of this manual lists replacement parts and
accessories for the CO

detector.

Description

s,

The 61-1004RK CO2 detector has four versions, the 61-1004RK-02 which has a detection
range of 0 - 5,000 ppm, the 61-1004RK-03 which has a detection range of 0 - 5% volume,

the 61-1004RK-05 which has a detection range of 0 - 50% volume, and the 61-1004RK-10
which has a detection range of 0 - 100% volume. The detector is an infrared type of
detector. This section describes the components of the 61-1004RK and 61-0191RK
detectors. The 61-1004RK includes the 61-0191RK detector and a junction box. A four
point terminal strip is provided inside the junction box for detector connections. The
61-0191RK does not include a junction box. Figure 1 below shows the components of the
61-1004RK.

61-0191RK Infrared CO2 Detector

The infrared CO2 detector is made up of a miniature infrared CO2 detector housed and
encapsulated in a pipe nipple. The pipe nipple has 3/4 inch NPT threads on each end and
a 1-1/4 inch hex that allow s removal or in stallation of the detector with a wrench. A
porous flame arrestor coated with a hydrophobic film that repels liquids is on one end of
the detector and allows sample gas to enter the detector. Four color coded leads, red,
white, green, and black, extend from the other end of the detector. The leads allow you to
connect the detector to the terminal block in the junction box.

To distinguish the different ranges of CO
shrink tubing is applied to the wiring where it comes out of the nipple. The following
table indicates the color of the shrink tubing and the color of the wire to which it is
applied.
