• Using a Virtual Main to Mitigate Your Arc Flash Hazard

  Using a Virtual Main to Mitigate Your Arc Flash Hazard What Is an Arc Flash? In electrical power systems, unwanted electrical discharge between conductors results in what is called an “arc flash”—the rapid release of energy in the air. These arc flashes release heat that is 35,000°F, creating a major risk of injury for those […]

• How Machine Vision Systems Can Improve Product Quality and Reduce Costs

  How Machine Vision Systems Can Improve Product Quality and Reduce Costs In manufacturing, microscopic particulates—often as small as 1/100th of an inch—can contaminate products during the manufacturing process. If left undetected, the manufacturer runs the risk of allowing low-quality products to end up in the hands of their customers. In these circumstances, it is wise […]

• Understanding and Preventing Fault Masking

  Understanding and Preventing Fault Masking It’s critical that industrial machinery stops safely when a system fault occurs.  However, older safety systems and complex systems with multiple safety switches may be prone to fault masking. Fault masking is a dangerous condition in safety circuits.  It results from daisy chaining multiple safety devices in a safety circuit, […]
