Abstract
Instrument to measure the sizes and quantities of particles in a fluid medium in which a light sensitive device, which converts light scattered by particles contained in a flow of a fluid medium that crosses a beam produced by a luminous source, as well as a part of the light of that beam that arrives from an element that simulates a calibrated particle, in electrical signals, is connected, through a divider whose purpose is to distribute these impulses, according to the particle sizes, to signal inputs of respective devices of threshold whose outputs are connected to inputs of counters with indicators, characterized in that the element that simulates a calibrated particle is intended to vary periodically, in the course of measurements, the brightness of a part of light received by the light-sensitive device and because interposed between the output of the light sensitive device and reference inputs of the threshold elements there is a circuit provided for converting output pulses of the light-sensitive device into a dc voltage which adjusts the trigger levels of the threshold devices according to the amplitude of a pulse produced by the element simulating a calibrated particle.
