Absolute method for dynamic reproduction of small pressures

Conclusions

• 1. Theoretical investigations have shown the possibility of measuring high vacuum by the pressure-reduction method.

• 2. The equipment produced by us provides a reproduction by the above method of small absolute pressures from 10⁻² to 10⁻⁴N/m².

• 3. The relative root-mean-square error of the equipment does not exceed 5% of the measured pressure.

• 4. The calibration of ionization-gauge transducers by the pressure-reduction method has confirmed the results obtained in calibrating them with the compression single-capillary manometer [12]. The calibration errors are approximately of the same order as those obtained in calibrating by means of a compression manometer.

• 5. The above dynamic method of reproducing small pressures has distinct possibilities for measuring considerably lower pressures than those attained at the present time and, in this respect, it is preferable to the mercury compression-manometer method.

• 6. Equipment used for implementing the above dynamic pressure-reduction method can serve as a reference absolute manometer within its pressure range.
