Sensor Orientation

WARNING! 

Mount the XIR PLUS with the sensor inlet fitting extended horizontally from the main enclosure (Figure 9 ) to prevent the build-up of particulate or liquid matter on the monitor's optical surfaces.

Mount the digital sensor with the sensor inlet fitting (Figure 10 ) pointed downward; otherwise, the inlet may become clogged with particulate matter or liquids.

Failure to follow this warning can result in serious personal injury or death.

Sensor orientation will depend on the sensor type. If mounting an ULTIMA XIR PLUS sensor, whether locally on the transmitter or via remote junction box, the sensor should be mounted horizontally. If the ULTIMA XIR PLUS sensor is not mounted horizontally, the sensor will be prone to more frequent beam blocking issues due to accumulated dust and condensation on the surface of the ULTIMA XIR PLUS sensor. Figure 9 shows the correct and incorrect mounting orientations for the ULTIMA XIR PLUS.

All other sensors including electrochemical, combustible catalytic bead, and oxygen sensors should be mounted vertically, with the gas inlet pointed downward. If the sensor is not mounted with the gas inlet facing down, it is more likely to become clogged with particulate matter or liquids. Figure 10 shows the correct and incorrect mounting orientation for digital sensors.
