We've relied on slip rings for many, many years to get essential signals from rotating segments of our equipment. Anyone who uses them in difficult, hot, dirty or less than perfect environmental settings struggles with maintenance and realibility. There's pressure for us to provide more data and more precise and reliable data from these points. This makes both operational and support issues a problem. There are wireless alternatives, but we haven't seen much evidence of them in tough, noisy environments. What do we need to know?
