Spectroscopic surface sensor StaRWIS monitors FSK Bridge in Maryland

In search of a suitable sensor for monitoring the Francis Scott Bridge in Maryland, Lufft USA's partner Communication Electronics, commissioned by the Maryland Transportation Authority, came across our new StaRWIS through our website.

In February 2018, they installed the StaRWIS on the Bridge and it has delivered satisfying results every since.

The sensor was convincing due to its easy installation, it's non-invasive operation, which doesn't affect the structural integrity of the construction and thus saved a lot of infrastructural work. Moreover, it is stable against vibrations, as they are common on bridges.

"The sensor has been working well over the 4 months it’s been operational", reported Scott Humphreys, project manager at Communications Electronics.
