Вимірювальні перетворювачі рівня молока з дискретним вихідним сигналом для молокоприймальної камери доїльного апарата

Abstract

In the article two variants of measuring transducers of the level of milk with a discrete output signal for the milk receiving chamber of the milking machine are considered. With the aid of such transducers, one-time lamb measurements, instantaneous milk yield intensity, average milk yield intensity, milk yield intensity during the first three thirty-second time intervals from the start of milking and the length of time of admission are possible. The proposed milk level measuring converters in milk receiving chamber of a milking machine with a discrete output signal (photoelectric and on the basis of MAE) are intended for use on steady milking units as part of portable milking machines and provide the necessary precision of the measurement transformation for controlling the milking process. On the functioning of the measuring transducer, the level of milk in the milk sampling chamber of the milking machine with a discrete output signal based on the MAE is not affected by the contamination of the milk receiving chamber, but it has moving parts, which reduces the reliability of its operation. Photoelectric measuring transducer of the milk level in the milk receiving chamber of the milking machine with a discrete output signal of the moving parts does not have, but its functioning can be influenced by the contamination of the milk receiving chamber
