The invention relates to a dendrometer based on a linear positioning sensor which transforms variations of the position of its corresponding piston, which is in contact with the plant, into voltage differences captured by an electronic recorder connected to the sensor, in the vicinity of same, by means of a cable consisting of three high-impedance wires, in such a way that the reading of the radial variations of the plant studied or measured is taken in volts, the ratio between voltage and length being 1 mV (4 micrometres). The precision of the device is determined by the capacity of the recorder, the resulting resolution for 12 bits being 0.61 mV (2.44 micrometres), enabling the study of the daily variations of the plant, generated by the hydric status of same, along with the accumulated radial growth of the stem or branches and the duration of the vegetative period.
