Abstract:
1. A measuring system for picking up structure-borne sound from machine elements in a machine housing wherein the machine housing has a lubrication hole opening; the measuring system comprising: a mounting pin to be fixed to the machine housing via the lubrication hole opening the mounting pin having a passage hole therethrough along a length of the pin for passage of lubricant through the pin into the lubrication hole opening, a housing to accommodate a printed circuit board therein; the mounting pin passing from the housing into the lubrication hole opening for mounting the vibration sensor housing to the machine housing, at least one printed circuit board having electronic components for signal evaluation and disposed in the housing, a vibration sensor housing, at least one vibration sensor in the vibration sensor housing arranged such that the sensor housing can be rotated with respect to the mounting pin as the mounting pin is screwed into the lubrication hole opening, the mounting pin being such that in the end position of the screwing-in of the mounting pin, the vibration sensor housing is connected to the machine housing via a bushing with a force fit and so the vibration sensor housing is thereby secured against rotation and the vibration sensor is adjacent to the bushing, whereby structure-borne sound is transmitted directly from the machine housing to the vibration sensor via the bushing.
