Special coatings can be applied to the board and its components to protect against the abrasive effects of dust particles. In a chemical processing plant where there is a risk of chemical splashes and fumes, the enclosure can be made from materials resistant to chemical corrosion, such as stainless steel or specialized plastic composites. It can also be sealed to prevent any harmful substances from reaching the internal components, and additional ventilation systems can be incorporated to manage any potentially explosive or harmful gas build-up.
  • Thermal Management: Depending on the ambient temperature conditions of the industrial setting, custom thermal management solutions can be incorporated. In a facility located in a hot climate where the board might be exposed to high temperatures for extended periods, additional heat sinks, cooling fans, or even liquid cooling systems (if applicable) can be integrated into the enclosure to maintain the device within its optimal operating temperature range. In cold environments like Arctic oil and gas exploration sites, heating elements or insulation can be added to the enclosure to ensure that the DS3800HUMB starts up and operates reliably even in freezing temperatures.
