When it comes to monitoring the condition of critical, slow-moving (0.25-80 rpm), high capital value plant and machinery, companies really need to consider the benefits of acoustic emission monitoring - particularly where there are fluctuating load conditions and where a breakdown would have a significant impact on production. As Ian Taylor, business development engineer plant condition monitoring at Corus Northern Engineering Services (CNES) explains: "Many companies rely on vibration monitoring systems to check the condition of critical plant and machinery, but this method is not as accurate as acoustic emission monitoring, especially when it comes to slow speed, fluctuating load applications.
