ACCURACY OF A BELLOWS VACUUM METER WITH AN LC-GENERATOR

摘要

Errors of pressure measurement are considered. The error as a function of the pressure for a vacuum gauge rated at up to 1000 Pa is calculated as an example. It is 0.15 ≤ δp/p ≤ 0.2% over a pressure range of 14≤ p≤ 1000 Pa and it increases hyperbolically up to 100% with p ≈ 0.01 Pa. The parametric reliability of the instrument and its immunity to an accidental increase in pressure the atmospheric level is substantiated.
