A monitoring device for monitoring crop yield is disclosed. The monitoring device is mounted to a housing of a grain elevator of an agricultural work machine proximate a crop conveyor assembly arranged in the housing and has at least one aperture formed therein. A material engagement member is arranged on the mounting structure and is pivotal with respect to the mounting structure about a pivot point. The material engagement member can comprise first end and a second end opposite of the first end. At least one rotational sensor is arranged in the monitoring device and is configured to detect spatial movement or position of the material engagement member. A processing device is coupled to the at least one rotational sensor and is configured to determine an aggregate crop yield based on the detected rotational magnitude of the displacement of the first end or second end.

A shot peening intensity measurement device has a holder and a test disk formed from a resonant and hardened material. The test disk is held to the holder with a cover that threads onto the holder and clamps the test disk. The holder and test disk form a chamber where a portion of the test disk is unsupported. A measurement device, such as a microphone or other non-contacting device detects vibrations from the test disk when shot or media contacts the test disk.

An assembly for measuring metal powder material mass flow rate during direct metal deposition is disclosed. A detection strip is placed in the gas-blown metal powder material flow path. The detection strip is fixed in one end and suspended at the other end. The flowing metal powder material particles induce displacement to the detection strip. A displacement measurement sensor measures the amount of displacement of the detection strip. The amount of displacement of the detection strip gives relationship to the amount of the metal powder material flowing in the metal powder material flow path. Preferably, the detection strip and the sensor are enclosed in a housing with a metal powder material inlet port and metal powder material outlet port and includes internal features for smooth travel of metal powder material particles.

A method of calibrating a yield sensor of a harvesting machine. The yield sensor generates a grain force signal as clean grain piles are thrown by the elevator flights against the sensor surface of the yield sensor. A grain height sensor is disposed to detect a height of the clean grain pile on each passing elevator flight. Each grain height signal is associated with a corresponding grain force signal by applying a time shift to account for a time delay between the time the grain height signal is generated and the time at which the impact signal is generated. The grain force signal is corrected by multiplying the grain force signal by a correction factor. The correction factor is the sum of the grain height signals divided by the sum of the grain force signals over a predetermined period.
