NTBE-SPM-TRIBO · Real-time in-situ SPM — triboelectric probe
Tribo Electric Dust Monitor (SPM)
Real-time, continuous indicative dust monitor with logging and alarm capability. A single probe installs into the silo or duct — ideal for thick-walled or double-walled ducts thanks to single-sided installation. Measurement is based on tribo-electric charge transfer: charge carried by dust particles is captured by a highly sensitive triboelectric probe, amplified and transmitted to the control unit. Current generated is proportional to particle concentration, giving an indicative SPM signal.
Key Features
