I know in modern day Radar systems that slip rings were eliminated by using a cable wrap system. This allows the antenna to swing +/- 400 degrees.
Sorry about the link. Old age setting in. http://www.carbonelorraine.com.ar/pdfs/electrolisis.pdfthere's no link in your post, but I think you are on to something there with the spring tension again. Every time the brushes are cleaned, they are pulled back to insert a cloth or whatever between the brush and the ring. this could explain why the problem happens exponentially more often. more failures leads to more cleaning which stretches the springs, which leads to more failures. I am going to see about getting new springs.
The PRB (Power Rail Booster) is intended for use as a network component in
electrical PROFIBUS networks. It's purpose is the amplification and safe, reliable
transmission of PROFIBUS signals. The PRB enables the transmission of
PROFIBUS signals over contact rails, loops and other cable types (such as
telephone cables) not compliant with the PROFIBUS Specification. The PRB also
enables data transmission in the face of an excessive EMC load.
The PRB can be easily integrated in existing PROFIBUS fieldbus networks. It is also
possible to configure a complete PROFIBUS fieldbus network in line and/or star
topology. Except for the Power Booster itself, no other filters or terminating elements
are required for safe, reliable data transmission.
I've had many people do that.so after all this research I've done on this stupid profibus transmission through sliprings crap, my boss comes to me today and tells me to start looking into wireless options. I wanted to shout "I've already done that! I brought you tons of information about it and you weren't interested!" Oh well, I get what I wanted from the beginning, and he gets to think that it was his idea; I guess it's a win-win of sorts
wow, so I guess it is a universal phenomenon. I wonder if there is some scientific significance to the 3 month constant?I've had many people do that.
I'll let them know something will work a lot better a different way, and they'll flaty refuse, but happily pay you to find a work-around. Once enough time has passed (about 3 months), THEY come back with your original plan and claim they found the solution, and ask why you never mentioned it to them. Even if you have notes and calendar history dates, they are ignored. It was THEIR idea now, so it can be used.
It's a universal Dilbert "pointy haired boss" phenomenon.
Not sure, but if it doesn't happen in 3, it comes back in 12 for sure. It's just bosses and having to admit they didn't know all they thought they did at the time, and after a certain period, enough new problems/projects have been in the middle where The Boss figures he can slip it back in as his idea.wow, so I guess it is a universal phenomenon. I wonder if there is some scientific significance to the 3 month constant?
