The SMC9004 series is designed for taking samples from rotary kiln exhaust gases. The system includes an automatic sampling oil-cooled sampling probe, a cooled heatsink, heated dust filter, and dust collector. The full sampling system and duct line are temperature controlled, and the programmable logic controller (PLC) automatically controls sampling, back-purging, calibration, and the pretreatment system.

At a glance
  • The pneumatically or electrically driven sampling probe can be manually operated
  • Full automatic control
  • High-precision, reliable original meters, low lag time
  • Stable, long continuous operation, long service life
  • The air motor that drives the automatic extraction device can be powered by the air reservoir, ensuring reliable operation even during abnormal conditions
