fellner engineering was founded in 2013 and began to develop a system for the acoustic monitoring of circular sawing systems.

For non-technicians, the functionality can be explained as follows:
In sawmills, the log to be cut is pushed at high speed (up to 200 m / min) through two saw shafts at the top and bottom, each with up to twelve saw blades. The load on the saw blades is very large, they begin to vibrate and heat up due to the friction in the kerf. As a result, it comes to dirty cuts and thus to committee. In severe cases, damage to the saw blades may occur. Thanks to our acoustic monitoring, this damage to the saw blades can be avoided, thus increasing the service life. This results in significant cost savings.

CSM Heartbeat is the only system in the world that uses this non-contact acoustic principle to protect the saw blades. It is still unrivaled and works very reliably. This is reflected in the now 80 installations worldwide.
