NTBE-SPM-LASER · Laser backscatter — opacity & smoke in flue gas
Back-Scattered Laser Dust Monitor (SPM)
Online dust monitor for continuous measurement of particulate matter concentration in industrial combustion or air-filtration exhausts. Uses mainstream laser backscatter measurement with imported core components. Suitable for standalone operation, as part of a CEMS, or networked with a shared acquisition & processing unit for multi-point dust monitoring.
Key Features
- ✓Laser backward scattering — immune to beam swing from vibration / uneven refractive index
- ✓Single-side installation, no optical alignment required
- ✓On-site local display of dust concentration
- ✓Modulated laser beam — high anti-interference
- ✓'No-tool' field installation design
- ✓4–20 mA standard industrial current output
- ✓Very low power (~3 W)
Applications
Stack emission monitoringBoiler & furnace exhaustMulti-point dust networksCEMS installations
