Source Interference
When multiple adjacent pipes, vessels, or conveyors have nuclear gauges, you
must consider the orientation of the source beams so each gauge senses
radiation only from its appropriate source. Maximize the distance between the
source holders when mounting them on adjacent vessels. Make sure to maintain
the appropriate source to detector distance as illustrated in Figure 4.3 .

4.5 Temperature
Your source holder may have components that are sensitive to temperature
extremes. Avoid exposure to temperatures beyond the specified limits.
The
maximum operating temperature for the vessel is + 260 °C (+ 500 °F). Consult the
factory if this temperature is exceeded.
Ambient Temperature
You may use the source holder in continuous ambient temperature conditions from
- 40 °C … + 60 °C (-40 °F … + 140 °F). Minimize direct exposure to sunlight when
ambient temperatures 40 °C (+ 105 °F).
