ABSTRACT:
In a food processing plant electronics used to monitor and control various food processing methods are subject to harsh environmental conditions such as thermal shock, outside contaminants and condensation. An electronics enclosure for minimizing such problems places the electronics in an interior enclosure which is separated from and surrounded by an exterior enclosure. Dry nitrogen gas is input to the interior box to create an internal pressure greater than ambient pressure. The gas is vented to the exterior box which is also maintained at greater than ambient pressure. Thermal shock is reduced by spacing the internal and external boxes apart using thermally non-conductive spacers.
