<p>The program control of a sterilization operation by superheated and saturated steam is based in both vacuum phases on a barometrically compensated negative pressure pick-up. This measures at the end of the prevacuum (rough) phase the degree of rarefraction of the air in the treatment chamber and releases the subsequent steam phase. If the necessary rarefraction has not been reached or a leakage exists, it stops the process. This saves textile articles from the steam phase if it were ineffective for sterilization. The rarefraction is measured independent of all barometric fluctuations.</p> |
