Field of application
The VISIC100SF tunnel sensor is an all-in-one solution for measuring visibility, CO, NO, and NO2 concentrations. The VISIC100SF is easy to mount, operate, and maintain. There is no need for alignment or parameter setting. With its IP6K9K enclosure rating, the VISIC100SF is able to withstand the harsh ambient conditions inside the tunnel, also tunnel washing operations. During the design phase, particular importance was placed on ensuring reliable operation and long maintenance intervals.
Ventilation control in tunnels
Measurement of visibility when the tunnel portal is shrouded in fog
Anywhere where air quality has to be measured and improved
Device properties:
Visibility measurement according to the scattered light principle
CO and NO concentration measuring in accordance with EN 50545
Software developed in accordance with EN 61508 (SIL1)
IP 6K9K enclosure rating thanks to a rugged stainless-steel housing
Fog compensation through integrated heating (option)
Benefits
One sensor for three measuring components
High levels of reliability and operational safety
No need for protective measures during tunnel cleaning
Flexible connection options, easy to extend and integrate into existing networks
Visibility measurement can be easily verified with a checking tool
Low level of effort due to simple mounting and quick commissioning
