The checklist of issues to consider when it comes to using automation technologies in extreme environment applications can be long.
Though all issues should be considered carefully, Dennis Wylie, ControlLogix product manager at Rockwell Automation (www.rockwellautomation.com), notes that these three steps should be considered first and foremost:
• Recognize the need. Be proactive and regularly assess the current condition and adequacy of your controllers before a crippling problem occurs.
• Consider the environmental requirements. Because every industrial or manufacturing operation has its unique internal and external environments, define the extremes that will affect the controls and let that data inform your decision about where those controls should be located.
• Match the controller to the specifications. Extreme-environment controllers function the same as standard controllers, but come with design enhancements that allow them to withstand specific environmental conditions. For example, conformal coating is used to protect control devices in harsh-gas environments. Take the time to learn about the enhancements used in devices designed for extreme applications to make sure you’re making the right decisions.
