Изобретение отиогитг  к измерительной технике .The invention of the instrument for measuring equipment.

Известно устройство дл  измерени  нат жени  магнитной ленты, содержащее тензочувствительные элементы, св занные с блоком регистрации через селективный усилитель и демодул тор , подсоединенный к генератору периодического напр жени . При измерении нат жени  магнитной ленты известным устройством наблюдаетс  значительна  погрешность результата измерени .A device for measuring the tension of a magnetic tape is known, which contains stress-sensitive elements associated with a recording unit through a selective amplifier and a demodulator connected to a periodic voltage generator. When measuring the tension of a magnetic tape with a known device, a significant measurement result error is observed.

Дл  уменьшени  погрешности измерени  предлагаемое устройство снабжено ньезокерамической пластиной, размещенной между теизочувствительными элементами и соединенпой с renepaTOpOiM периодического напр жени .To reduce the measurement error, the proposed device is equipped with a ceramic plate placed between the sensing elements and connected to a periodic voltage renepaTOpOiM.

На чертеже изображен вариант описываемого устройства, содержащего пьезокерамическую пластину 1, смонтированную с возможностыо сопр жени  с магнитной лентой 2 между нанравл ющими роликами 3. Пьезокерамическа  пластина 1 подключена к генератору 4 периодического напр жени  и размещена между тензочувствительными элементами The drawing shows a variant of the described device comprising a piezoceramic plate 1 mounted to interface with a magnetic tape 2 between the pickling rollers 3. The piezoceramic plate 1 is connected to a periodic voltage generator 4 and placed between strain-sensitive elements

5, св занными с блоком 6 регистрации через селективный усилитель 7 и демодул тор 8, подсоединенный к генератору 4 периодического напр жени .5, connected to the recording unit 6 via the selective amplifier 7 and the demodulator 8 connected to the periodic voltage generator 4.

В процессе измерени  пат жени  магпитной ленты 2 привод т в состо ние высокочастотных колебаний пьезокерамическую пластину. Величина этих колебаний зависит от нат жени  магнитной ленты 2. Благодар  этому на вход блока 6 регистрации поступает сигнал, пропорциональный изменению нат жени  магнитной ленты 2.In the process of measuring the patching of the magnet tape 2, the piezoceramic plate is brought into a state of high-frequency oscillations. The magnitude of these oscillations depends on the tension of the magnetic tape 2. Due to this, the input of the recording unit 6 receives a signal proportional to the change in the tension of the magnetic tape 2.
