Because solids applications can be tricky, a new parabolic antenna has been developed for the Rosemount 5402 non-contacting radar. The new antenna includes a swivelling connection which makes it possible to aim the antenna at the best point in the silo, and also adjusts for angled silo roofs - making it suitable for most solids applications.
An air purging connection is also included to help prevent clogging of the antenna in extremely dusty environments and applications prone to product build-up. You can read more about it here http://www2.emersonprocess.com/siteadmincenter/pm%20rosemount%20documents/00813-0100-4026.pdf
You can actually measure up to 105 ft. now with the parabolic antenna on solids!
