At the suggestion of a leading company in the wood industry, fellner engineering GmbH was founded in Lower Austria in 2013 to develop a system for the acoustic monitoring of circular saw plants. Just one year later, the first "CSM Heartbeat" systems were ready for installation. The company's experts are now at LIGNA 2019 to show just how far their system has come since then.

"CSM Heartbeat" was created to tackle an all-too-common problem. In sawmills, logs are pushed at a relatively high speed - up to 200 meters a minute - through two upper and lower saw shafts with up to twelve saw blades each. As you'd expect, the saw blades are put under a great deal of strain. Quite often, they start to oscillate and heat up considerably due to the rubbing in the kerf. This, in turn, can produce wood with badly cut edges that often ends up on the scrap heap. In extreme cases, it can even damage the saw blades. By performing acoustic monitoring, "CSM Heartbeat" can recognize when the blades oscillate and recommend countermeasures. As a result, the system prevents damage to the saw blades, increases their service life, and is even said to reduce wastage. All this ultimately translates into significant cost savings - the perfect reason to keep your ears open!
