Figure 4: Sample Gas Feed Unit SCC-F
The sample gas feed unit sucks the sample from the exhaust gas
and continuously feeds the gas analyzer with the sample gas.
The pump is a diaphragm pump. If the pump fails a flow alarm
occurs.
Flow control
The flow meters monitor the sample gas flow through the
analyzer.
The following parameters are considered:
• Typical flow: 60 l/h
• Minimum flow level: 40 l/h
• Maximum flow level: 80 l/h
• Flow error: 10 l/h
If the flow violates a limit value an alarm is displayed on the front
panel. In addition, the sample probe is automatically
backpurged.
