Description

Изобретение относитс  к измерительной технике и может быть применено дл  исследований колебаний скорости движени  магнитной ленты в лентопрот жных механизмах устройств магнитной записи сигналов и звука. The invention relates to a measuring technique and can be applied to the study of fluctuations in the speed of a magnetic tape in tape recording mechanisms of magnetic signal and sound recording devices.

Известные устройства, содержащие корпус с чувствительным элементом и регистрирующий прибор, искажают характер движени  исследуемого объекта.The known devices, comprising a housing with a sensitive element and a registering device, distort the nature of the movement of the object under study.

Цель изобретени  - повышение точности измерени  поперечных колебаний.The purpose of the invention is to improve the accuracy of measuring transverse vibrations.

Это достигаетс  тем, что корпус выполнен с закругленным ребром, размещенным у ленты .This is achieved by the fact that the body is made with a rounded edge placed near the tape.

На чертеже показано предлагаемое устройство .The drawing shows the proposed device.

Лента 1 движетс  с заданной скоростью по заданному направлению. Дл  измерени  колебаний скорости движени  ленты установлен датчик 2, содержащий корпус с закругленным ребром 3 и чувствительный элемент 4. Закругление служит дл  подсоса воздуха во врем  равномерного движени  ленты. Благодар  равномерному подсосу воздуха воздущна Tape 1 moves at a given speed in a given direction. A sensor 2 is installed to measure fluctuations in the speed of movement of the tape, comprising a housing with a rounded edge 3 and a sensing element 4. The rounding serves to draw in air during the uniform movement of the tape. Thanks to the uniform air suction air

прослойка между лентой и датчиком имеет носто нное давление, а сигнал, выдаваемый чувствительным элементом - посто нный характер .the space between the tape and the sensor has a constant pressure, and the signal emitted by the sensitive element is constant.

При колебании ленты мен етс  давление подсасываемого воздуха, а значит и выдаваемый сигнал чувствительным элементом. Чувствительным элементом служат, например, пьезо- или кварцевые кристаллы, или тензодатчик , соединенный с регистрирующим прибором 5, который показывает колебани  скорости движени  ленты.When the belt oscillates, the pressure of the drawn-in air changes, and hence the outputted signal by the sensitive element. Sensors are, for example, piezo or quartz crystals, or a strain gauge connected to a recording device 5, which shows variations in the speed of the tape.

Предмет изобретени Subject invention

Устройство дл  измерени  колебаний движени  ленты, содержащее корпус с чувствительным элементом, подсоединенным к регистрирующему прибору, отличающеес  тем, что, с целью повыщени  точности измерени  поперечных колебаний, корпус выполнен с закругленным ребром, размещенным у ленты .A device for measuring oscillations of a tape movement, comprising a housing with a sensitive element connected to a recording device, characterized in that, in order to improve the accuracy of measuring transverse vibrations, the housing is made with a rounded edge positioned at the tape.
