Explosion-proof Delta F Oxygen Cells
Figure 21 below shows the explosion-proof oxygen cell. The oxygen cell has a set of sensing and a set of secondary
electrodes that are wired to a terminal strip in the explosion-proof enclosure. Connect the explosion-proof oxygen cell
using a four-wire shielded cable. Connect one end of the cable to the
moisture.IQ and the other end to the terminal strip in the oxygen cell enclosure. Feed the cable wires through one of the
cable ports in the side of the explosion-proof enclosure. Refer to Figure 18 on page 22 and Table 4 below for the
required connections.
