ГАЗАGas

Claims (1)

Формула изобретенияClaim Способ измерения давления реэреженного газа, основанный на отборе пробы газа в предварительно обезгаί женную камеру.и его сжатии, отличающийся тем, что, с целью повышения точности и расширения диапазона измерения,отбор пробы газа и его сжатие осуществляют молекулярI ным насосом с ротором на магнитной подвеске, а значение давления исследуемого газа определяют по градуиро» вочной зависимости значения давления газа от скорости вращения ротора при заданном· давлении пробы газа.A method of measuring the pressure of re-rarefied gas, based on sampling a gas into a pre-annealed chamber and compressing it, characterized in that, in order to increase the accuracy and extend the measuring range, gas sampling and compression is carried out by a molecular pump with a magnetic rotor and the pressure value of the test gas is determined by the gradual dependence of the gas pressure on the rotor speed at a given · pressure of the gas sample.
