Tunnel visibility sensor VISIC100SF series

•One sensor for three measuring components •High levels of reliability and operational safety •No need for protective measures during tunnel cleaning •Immune to gantry fog •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 Modernizes measurement performance for tunnel air quality The VISIC100SF tunnel sensor is an all-in-one solution for measuring visibility, CO, NO, and NO2 concentrations. It is exceptional solution that combines the scattered light measurement principle with electrochemical sensors – all in one compact housing. The VISIC100SF is easy to mount, operate, and maintain. There is no need for alignment or parameter setting – measuring starts right away. With its IP6K9K enclosure rating, not only is the VISIC100SF able to withstand the harsh ambient conditions inside the tunnel; it can also endure tunnel washing operations without any problems. During the design phase, particular importance was placed on ensuring reliable operation and long maintenance intervals. That is why there are no moving parts. To compensate for fog, there is an optional version available with heating. The VISIC100SF is a solution that meets desired requirements and is ideal for any tunnel application. At a glance •Visibility (K value) measured according to the scattered light measurement principle •CO and NO concentration measured using electrochemical sensors in accordance with EN 50545 •Software developed in accordance with EN 61508 (SIL1) •Highly reliable – no moving parts
