3. The limiting factor regarding the service life of the SmartSensor is that of contaminating the SmartSensor 1 through the taken in the air by small particles capable of passing through the front filter Part No 23002 and entering into the ionization chamber and 2 by larger particles which block the filter element thereby reducing its filtering capacity Thus the result is a strong dependence of the service life on the ambient conditions Any contamination in the ionization chamber results in a more noisy output signal from the SmartSensor making itself felt through fluctuations and sudden changes of the Zero line The SmartSensor must be considered as worn out when these fluctuations compared to the set up limit become too great However measurement sensitivity is maintained at an unchanged level over the entire utilisation duration In the case of an extreme contamination it can happen that the SmartSensor cannot be initialised any more when starting the system The reducing permeability of the filter element for air is compensated for by increasing the operating vacuum within a wide range But in the case of severe contamination the vacuum increases to such a level that the discharge within the SmartSensor becomes unstable or is extinguished without any apparent reason The filter element must be considered as worn out when this occurs frequently or when the ignition in the SmartSensor cannot be started When starting the system the
