Description
(54) УСТРОПСТВО ДЛЯ ИЗМЕРЕНИЯ РАЗНОСТИ ДАВЛЕНИЙ(54) TOOL FOR MEASURING DIFFERENT PRESSURE
Второй их конец закреплен на металической решетке б, котора может перемещатьс благодар наличию микрометрического , винта 7. Штуцера 8 и 9 служат дл подведени измер емых давле- с НИИ. Тензопленки 3 и 4 включены в два плеча мостовой схемы 10. В диагональ моста включен регистрирующий прибор 11, фиксирующий разбаланс моста.Their second end is fixed on a metal grating b, which can be moved due to the presence of a micrometric screw 7. Fittings 8 and 9 serve to sum up the measured pressure from the scientific research institute. Tenzofilki 3 and 4 are included in the two arms of the bridge circuit 10. The diagonal of the bridge includes a recording device 11, fixing the imbalance of the bridge.
Устройство работает следующим обра- .„ эом.The device works as follows.
Под действием измер емой разности давлений диафрагма 2 прогибаетс и измен ет сопротивление тензопленок 3 и 4; за счет прогиба св занных с ней подложек 5. Это изменение сопротивлений, пропорциональное разности давлений, измер етс мостовой схемой 10.Under the action of the measured pressure difference, the diaphragm 2 bends and changes the resistance of the tensor films 3 and 4; due to the deflection of its associated substrates 5. This change in resistance, proportional to the pressure difference, is measured by the bridge circuit 10.
Устройство обеспечивает измерение 20 разности давлений с высокой точностью; вплоть до 0,1 мм вод.ст. и найдет . применение в шелководстве и р де других областей.The device provides measurement of 20 differential pressure with high accuracy; up to 0.1 mm of water. and find. application in sericulture and a number of other areas.
