A structure-borne sound sensor detects vibrations that occur due to mechanical defects on the raceways or rolling elements. It can therefore only send a warning when bearing damage has already occurred. HCP Sense, on the other hand, monitors the causes of damage, load and lubrication, and can thus warn of harmful conditions at an early stage, before damage occurs. In addition, vibration sensors are often too far away from the bearing to provide meaningful data. In contrast, HCP Sense data is extracted directly from the bearing.
