DEVICE FOR STUDYING STRENGTH PROPERTIES OF TUBEROUS ROOTS Russian patent published in 2017 - IPC G01N3/40 

FIELD: agriculture.

SUBSTANCE: device comprises the fixed frame, the vertical movement mechanism with the pressure indicator; the rod is fixed in the fixed frame guides, consisting of two parts: the upper one and the lower one, wherein the lower part is inserted into the upper one with the possibility to move; a spring is mounted between the upper and lower parts of the rod in cups. The transmission mechanism of the writing device pointer with the strain gauge sensor transmitting the resistance changes to the computer, is coupled with the upper and the lower cups.

EFFECT: weight reduction, reducing the overall size, improving the measurements accuracy.
