Presentation

Michigan Scientific’s B Series Slip Ring Assemblies B4-3.2, B6-3.2 allow measurement signal transmission (thermocouples, strain gages, accelerometers) from a rotating shaft up to 51mm. The transmission is based on electric connexion between measuring signal circuits (rotor) and the stator. They are the result of 60 years of experience and the slip ring brushes and rings are made of precious metals which minimize noise and enable the assemblies to be used for low level instrumentation signals.

The B4-3.2, B6-3.2 slip rings have resp. 4 and 6 circuits, allowing the acquisition of up to 2 full strain gage bridges or 6 thermocouples. As this assembly uses permanently lubricated bearings and solid silver alloy, along with their high quality contacts, slip rings can be used constantly without any particular care. Degradation of the signal's quality can be observed after 50 to 100 million revolutions, more or less 100 000 kms on a standard passenger vehicle.

Mounting and dismounting

The B4-3.2, B6-3.2 can easily be mounted by positionning the diameter shaft inside the rotor. In this version, the 50.8mm diameter can be adapted to smaller axial measurements. The slip ring assembly is secured to the shaft with six 8-32 set screws.

Connections are made through color coded solder terminals located on the slip ring rotor and a connector on the slip ring stator. Redundant terminals are included to provide back-up connections. The compact width design of these slip rings makes them ideal for applications where limited space is available.

Collecting the stator's measurement signal is easily done by using the provided Bendix connector. No additional setup is required. The slip ring can be mounted and used in any application. Another great feature is the limited space it takes: 26mm.
