Controls and displays
The control cabinet is the central control point of the sampling system. The
electric power supply and signals for the entire sampling system are connect-
ed and distributed here. It is contains the display and operating unit for moni-
toring and operating the system.
The control program is equipped with various locking mechanisms that pre-
vent damage to the gas sampling probe due to incorrect operation or failure
of individual modules. If not all locking conditions are met, operation is not
possible. This safeguard is only overridden by personnel safety measures.
The picture shows controls on the control cabinet (side view left, front oper-
