Compact speed monitors for hazardous areas are specialized devices designed to ensure safety in environments with explosive or flammable conditions. These monitors are typically produced by industrial automation and safety equipment companies, such as those based in Germany (e.g., Pepperl+Fuchs) or the USA (e.g., Banner Engineering). They serve industries like oil and gas, chemical processing, and mining, where precise speed monitoring of conveyors, motors, or rotating equipment is critical. Key products include intrinsically safe speed sensors, rugged compact monitors, and explosion-proof tachometers, often certified to ATEX or IECEx standards for hazardous area compliance.
