Gas sensor system

Abstract

A gas sensing tube includes an outer surface, and an inner surface defining a passage. A sensor node is arranged along the sensing tube. The sensor node includes an inlet fluidically connected to the passage, an outlet fluidically connected to the passage, and an interior chamber arranged between the inlet and the outlet. A sensor cable extends along the sensing tube. The sensor cable includes a first conduit having a first connector coupled to the sensor node at the inlet and a second conduit having a second connector connected to the sensor node at the outlet. The sensor cable has a first conductor extending through the first conduit and being coupled to the first connector and a second conductor extending through the second conduit and being coupled to the second connector.
