Have you ever worked in a production plant? I did. It was my first full-time job after acitve-duty military service. I was a Production Supervisor (Foreman) at a metals manufacturing facility in St. Louis. The one thing I remember was we were always told to get "leaner." Spend less. Keep fewer things on the shelf...but keep the plant running!
This makes me appreciate the same situation several of our customers are in. Do more with less. Hence, a one size fits all radar suggestion - so one radar - (with a little bit of adjustment) can work in several different applications.
Using an example of an 80 GHz LR754FWB0021C410130GP0100 (list price as of June 26, 2020 is € 2703)
which has an ISO228-1 G 1½ A threaded process connection (GP0), the fittings aftermarket allows a threaded connection to become a sanitary BSP/Tri-Clover/Tri-Clamp, etc. connection.
Ordering a fitting such as this instantly transforms the threaded connection that's kept on the shelf:
Or an NPT as an alternate example:
Add the flexibility of using a 316L low-pressure flange disc (found at: https://schneider-electric.app.box.com/s/11d4tzlfks0j20uovirq5vmqahxg3c7n and available at www.buyautomation.com) with a "G" or "NPT" process connection and a threaded connection now easily fits into a flange connection.
To add to the sanitary application, it may also be of interest to verify the actual process wetted material in the example radar (PEEK and FKM) are FDA approved. See the attachments as an example.
