Oxygen sensor
The instrument is equipped with an oxygen measurement sensor to ensure a safe
operation when spraying combustible solvent. The inertization of the instrument is
continuously monitored. In case of an oxygen concentration above 6% the
instrument is able to immediately stop the solvent spraying. A safe state will be
reached with a maximum time delay of 15 to 25s. The actual time delay depends on
the drying gas flow rate.
The used sensor is SIL capable.
