Description
Table 27 and Table 28 above list the available infrared methane sensor configurations. The
infrared methane sensor is a smart sensor that stores the target gas.
Figure 42: Typical Infrared Methane Sensor Location
The infrared methane sensor is installed in a single sensor flow chamber which is located
in the area next to the standard 4-sensor flow chamber. This area can accommodate up to
three single sensor flow chambers. Figure 42 above illustrates a typical infrared methane
sensor location in front of the pump. The infrared methane flow chamber may also be
installed in one of the other two sensor chamber locations depending on the particular
version of the EAGLE 2. Some infrared methane instrument configurations do not include
the 4-sensor flow chamber.
Infrared Methane Sensor
The infrared methane sensor is a cylindrical sensor with a diffusion opening on the front
and a 12 pin circular connector on the back. A 12 wire cable plugs into the back of the
infrared methane sensor with a circular connector that includes a locking lever. The other
end of the cable plugs into an infrared sub PCB (see description below) that is installed on
the main PCB. The sensor is held in the infrared flow chamber by a bracket on standoffs.
