An apparatus for use during drilling of a wellbore. The apparatus includes a receiving device that receives cuttings from a separator and a sensor for providing information relating to weight of the cuttings received by the receiving device for determining the weight of the cuttings received. A method is provided for determining an amount of cuttings received in a fluid from a wellbore by separating the cuttings from the fluid, receiving the separated cuttings on a member, and determining weight of the cuttings received using a sensor associated with the receiving device.

Apparatus and method for separating and weighing cuttings received from a wellbore while drilling

A method for the signal processing of capacitive measurement scales intended for the measurement of lengths or angles, consisting of two parts moveable relative to each other provided with electrodes that together form condensers, whose magnitudes are variable and depend on the relative position as specified by a sinusoidal relationship between the two parts. The first part has n electrodes evenly distributed over one measurement period and the second part has one electrode per measurement period. The electrodes in the first part are fed with n alternating voltages whereby the time displacements of the alternating voltages relative to each other are , where tis the length of the period of the alternating voltage. The electrode of the second mobile part captures a signal composed of one or several of the alternating voltages and the amplitude composition of the signal depends on the relative position between the two parts.
