Chapter 1. Installation and Wiring

1.8.4 Pressure Sensors

If a pressure input is required and if an optional pressure signal is not available from a Moisture Image Series probe,
you can connect a separate pressure transmitter to an auxiliary input.
The moisture.IQ accepts any 0 to 20-mA, 4 to 20-mA, or 0 to 2-V pressure transmitters.
Always mount the pressure transmitter directly downstream from the moisture probe to ensure that the pressure is
measured at the same point as the moisture measurement.

1.8.5 Delta F Oxygen Cell

Although the moisture.IQ accepts other oxygen devices as auxiliary inputs, it is designed to accept oxygen inputs
directly from the Delta F Oxygen Cell. There are three steps for installing the Delta F Oxygen Cell:
1. Prepare the oxygen cell for operation
2. Calibrate the oxygen cell.
3. Connect the oxygen cell to the gas line.
The Delta F Oxygen Cell is available with various types of mounting enclosures. However, the cell itself will always
look like the one shown in Figure 7 below.
