Field of application
The VICOTEC450 draws air from inside the tunnel and determines the visibility with a high level of accuracy using scattered light technology. It regularly and automatically carries out a functional test including the function of the laser and receiver as well as the contamination of the optics. Maintenance requirements for cleaning and filter exchange are automatically registered and signaled in time by the VICOTEC450 due to contamination check and measurement of the air flow rate (optional).

Visibility monitoring in tunnels for ventilation control

Smoke detection in tunnels

Device properties:

Regular functional test with contamination measurement

Linearity test can be carried out with filter set

Internal purge air for long intervals between cleaning

Maintenance signal (filter and cleaning)

Logbook function

Extendable with various interfaces or I/O modules

Benefits
Very reliable operation due to full self-test

Cost-effective and fast commissioning (no optical alignment required on site)

Flexible electrical integration thanks to the easy connection of additional interfaces or I/O modules.
