Abstract
РЕФЕРАТ I 1. Об'єкт винаходу: Пристрій для виміру тиску. 2. Галузь застосування: Контрольно-вимірювальна техніка. 3. Суть винаходу: Пристрій складається з двох джерел постійної напруги, які здійснюють через чутливий до тиску резистор живлення двох польових тран зисторів. Витоки польових транзисторів з'єднані між собою. Паралельно сто кам польових транзисторів підключене послідовне коло з пасивної індуктив- ності і конденсатора. При дії тиску на чутливий до тиску резистор змінюється його опір, що приводить до зміни ємнісної складової повного опору на елект родах сток-сток польових транзисторів, а це викликає зміну резонансної час тоти коливального контуру (1 іл.) 4. Технічний результат: підвищення діапазону виміру тиску.ABSTRACT I 1. Object of the invention: Device for measuring pressure. 2. Field of application: Control and measuring equipment. 3. The essence of the invention: The device consists of two sources of direct voltage, which are carried out through a pressure-sensitive power resistor of two field-effect transistors. The sources of field-effect transistors are interconnected. A series circuit of passive inductance and a capacitor is connected in parallel to hundreds of field-effect transistors. Under the action of pressure on a pressure-sensitive resistor, its resistance changes, which leads to a change in the capacitive component of the impedance at the electrodes of the drain-drain field-effect transistors, and this causes a change in the resonant frequency of the oscillatory circuit (1 Fig.). pressure measurement.
