Structure-borne sound sensors are used to measure vibration and variations of force on machine parts for purposes of quality assurance and early detection of damage.
The sensing pin is connected to the surface of the measured object via a spring. The sensor is threaded so it can be screwed into an external mounting. A sound wave traversing a solid body generates a load difference in the sensor. This is then processed as a voltage signal.
The structure-borne sound sensor features a simple and robust design. It requires no external voltage supply.
