The infrared methane sensor is known to not or to poorly respond to the
following combustible gases:
•acetylene
• benzene
• hydrogen
Description
Table 26 and Table 27 above list the available infrared methane sensor
configurations. The infrared methane sensor is a smart sensor that stores the
target gas.
Figure 40: 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 40
above illustrates a typical infrared methane sensor location in front of the
