System for mounting a vibration transducer at a machine

A system for vibration measurement at a machine, comprising:

• a mounting pad made from ferrous magnetic material and configured to be mounted at a measurement location of the machine;
• a vibration transducer unit;
• and
• a magnetic base comprising a transducer fixation structure configured to releasably fix the vibration transducer unit at the magnetic base and a pad engagement structure configured to releasably engage with a mating engagement structure of the mounting pad so as to magnetically fix the magnetic base at the mounting pad for vibration measurement;
• wherein the engagement structure of the mounting pad comprises at least one groove and is asymmetric in a direction orthogonal to the longitudinal direction of the at least one groove in such a manner that engagement of the engagement structure of the mounting pad with the pad engagement structure of the magnetic base defines an orientation of the magnetic base with regard to the mounting pad in an unambiguous manner so as to ensure proper orientation of the transducer unit with regard to the machine.
