CASE STUDY

Sealed Industrial Slip Ring Provides Clean, Noise-Free Signals in Extreme Oceanographic Environments

A worldwide designer and manufacturer of bottle filling and capping systems has relied on Meridian Laboratory’s multi-channel, Ethernet-equipped sealed slip rings for over 25+ years to provide maintenance-free, rotary electrical connections to all of their machines.  After struggling for years with Ethernet communication packet loss and consistently having to maintain or replace brushes, they were able to eliminate all of these issues by switching to ROTOCON rotary electrical connectors.

Challenge

A manufacturer of oceanographic winches and test equipment contacted Meridian Laboratory about numerous issues with conventional slip rings used on its vessels’ deep-sea winch assemblies. Issues included noise generated by slip ring brushes, contact resistance making signal strength weak and unrecognizable, and arcing (cross-talk) occurring between channels due to wet, humid oceanographic environments.

  • Noise generated by conventional slip rings made signals unrecognizable and distorted.
  • Saltwater environment corroded brushes and decreased slip ring longevity.
  • Slip rings required routine maintenance and retrofitted protective equipment.

 

Solution

Using Meridian Laboratory’s unique ROTOCON® MXO Series of oceanographic/harsh industrial environment rotary electrical contacts, the manufacturer eliminated all prior issues it had with conventional slip rings. The inherent qualities of ROTOCON’s low contact resistance (low noise) design allowed for signal integrity of water temperature and cable strain to be maintained. In addition to the stainless steel design and added sealing capability of the MXO series, the customer was able to specify a particular sub-sea connector which would directly mate to all existing equipment without any extra modification. This custom solution provides extreme ingress protection while the unit remains maintenance-free with uninterruptable operation for many years, despite its wet, humid and corrosive operating environment.

  • ROTOCON’s unique design characteristics provided clean, noise-free signals for test and measurement in harsh oceanographic environment.
  • Stainless steel construction with sub-sea connectors provided 100% sealed design.
  • Slip ring downtime drastically decreased without issues of corrosion, maintenance or cross-talk.

Underwater Slip Ring

 Key Statistics

  • ROTOCON® Sealed slip ring provides clean signal quality, regardless of temperatures or environment.
  • 100% maintenance-free alternative without needing adjustments or upkeep.
  • Downtime drastically reduced by improved slip ring allowing for cost savings and improvement in measurement quality.

    I purchased some hubbed rollers for a personal project I am working on. The sales team was VERY helpful and provided me with … More a sample kit which guided me to the right roller for my application. The rollers I received were really good quality and worked perfectly for what I needed. Would definitely recommend if you need polyurethane rollers for any projects.

    Worked with Vance on getting some rollers for an application of ours. He is very knowledgeable and was able to get the rollers … More for my company in a timely manner. Had an issue with one of the rollers and he replaced it for free! I am sure they took that roller apart and studied why it was rolling "rough". I really appreciate the time, the quick response, and how things were handled. Thank you Vance!
