Description
ответствующей коэффициенту преобразовани преобразовател (в месте нахождени пьезокерамики - амплитуда наибольша , по мере удалени от пьезокерамики амплитуда уменьшаетс .corresponding to the conversion ratio of the transducer (at the location of the piezoelectric ceramics — the amplitude is greatest; as the distance from the piezo ceramics increases, the amplitude decreases.
Поэтому на экране осциллографа по вл етс картина амплитуд по длине преобразовател (см. фиг. 2). Конструктивно барабан выполн етс таким образом, чтобы при соударении стержней с поверхностью преобразовател сила удара соответствовала бы падению зерна с определенной высоты. Дл этого производитс выбор угла наклона преобразовател и его положени относительно стержней барабана.Therefore, a picture of the amplitudes along the length of the transducer appears on the oscilloscope screen (see Fig. 2). Structurally, the drum is designed so that when the rods collide with the surface of the transducer, the impact force would correspond to the fall of the grain from a certain height. To do this, select the angle of inclination of the transducer and its position relative to the drum rods.
Врем нанесени ударов (скорость вращени барабана) и скорость развертки подбираютс таким образом, чтобы получить неподвижную картину на экране осциллографа.The time of striking (the speed of rotation of the drum) and the sweep speed are selected in such a way as to obtain a fixed picture on the screen of the oscilloscope.
Предмет изобретени Subject invention
Устройство контрол коэффициента преобразовани преобразователей датчика потерь зерна, состо щее из осциллографа, двигател , основани , вращающегос барабана с имитирующими стержн ми, отличающеес тем, что, с целью автоматизации контрол и повышени его точности, стержни расположены па барабане по винтовой линии с щагом, равным длине его, соответствующей длине преобразовател .A device for monitoring the conversion rate of the grain loss sensor transducers, consisting of an oscilloscope, a motor, a base, a rotating drum with imitating rods, characterized in that, to automate the control and increase its accuracy, the rods are located on the drum along a helix with a pinch equal to its length corresponding to the length of the converter.
