ABSTRACT:
The grain-loss detector according to this invention usable in combination with a harvesting machine having an output passage comprises an impact plate having a front face exposed in the passage for direct contact by crop exiting the machine and an opposite back face and an electroacoustic transducer capable of converting vibration into an electrical output and having a side directly engaging the back face of the impact face. According to this invention the side of the transducer is retained in direct contact with the back face of the impact plate and electronic elements spaced from the transducer serve to convert the output of the transducer into a usable data signal.
