摘要： Measuring the electrical resistance of a resistive body, in particular a reservoir containing a printing product such as ink. According to the invention, the resistive body is used to define a capacitance arrangement formed from a capacitive branch which includes a capacitor electrically connected to the resistive body and this is incorporated in a resonant circuit that includes a variable capacitor. The resonant circuit is supplied with a fixed frequency, and as the capacitance of the variable capacitor is varied the peak of the signal is sought. The amplitude of the peak is representative of the resistance of the resistive body.

摘要： The object of the invention is the detection of a given threshold (optionally zero) for filling, with an electrically conductive product, a reservoir made of electrically insulating material having a storage cavity connected to an outlet channel. An excitation signal is applied to the cavity, in periodic square waves, and a measurement signal is taken off, one characteristic of which varies substantially with the quantity of product contained in the cavity reaches the filling threshold. From this characteristic, by comparison with a reference threshold, a binary signal C,C′ is derived, which is filtered digitally whilst multiplying it (convolution product) by a signal which is identical to it, but with a delay equal to a multiple, at least equal to one, of the period of the square waves.

A resonant circuit is formed, including a capacitive arrangement formed at least part from the reservoir. A measurement procedure is defined according to which a plurality of excitation signals are applied to the resonant circuit having different frequencies, and a plurality of measurement signals are made. A processing procedure is defined which identifies the instantaneous resonant frequency of the resonant circuit, measures the width, for a given amplitude level, of the resonance peak, and derives therefrom an item of information representing the quantity of product contained in the storage cavity. At least one determination cycle is effected, consisting of triggering the measurement procedure and the processing procedure, and capturing the instantaneous value of the item of information.

摘要： Determination of the quantity of liquid product contained in a reservoir, with the help of a capacitive arrangement. The invention is applicable to a reservoir (112) comprising a compartment (166) where the product is in the captive state, for example impregnating a porous body, and the conductive electrodes (221, 222) associated with this compartment are situated on either side of the volume where the product is in the captive state and offset with respect to one another in order to be located respectively in the vicinity of two opposite ends of this volume. When the reservoir has another compartment where the product is in the free state, the electrodes of the capacitive arrangement are advantageously L-shaped.
