METHOD FOR TRACKING THE GROWTH OF THE DIAMETER OF A TREE BODY Russian patent published in 2022 - IPC G01B5/08 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to the field of mechanical engineering, in particular to methods for monitoring the increase in the diameter of tree trunks. A method is proposed, in which a device is used, containing a body with a support foot, on which a clamp is fixed. Two coils are installed inside at the same horizontal level. One of the coils is mounted on the rotary knob of a variable resistor with a linear characteristic. A measuring tape is wound on the other spool. Wires are connected to the contacts of the variable resistor, which are led outside the case. The tree trunk is covered with a collar fixed on the support leg of the body. The coil mounted on the handle of the variable resistor is turned to its extreme end position. A measuring tape is wound from the other reel. A tree trunk is then covered with it. The free end of the measuring tape is fixed on a coil mounted on the handle of a variable resistor. The coil is turned, while winding a measuring tape around it, until the rotary knob of the variable resistor is set to its original position. The position of the coil, from which the measuring tape was wound, is fixed in a fixed position relative to the body. An electronic computer is connected to the wires brought outside the case.

EFFECT: reduced labor intensity of work on monitoring the increase in the diameter of the trunk.
