Michigan Scientific’s BX-2W Weatherproof Slip Ring Assembly is ideal for applications that require the slip ring to be sealed and mounted directly on a rotating shaft. Typically used for automotive drive shaft measurement applications, this model employs specially designed seals that provide weatherproof protection from water, mud, snow, dust, and other contaminants. It is designed to fit on shafts up to 2” in diameter and make an electrical connection to strain gages, thermocouples, or other sensors that have been installed on a rotating shaft in rotary equipment. 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 six circuit capacity of this slip ring allows for more than one full bridge strain gage measurement channel. This is useful for drive shaft applications where both torque and axial measurements are needed. The BX-2W also provides enough circuit connections for use with spinning amplifiers. Locating precision amplifiers on the rotating side of the slip ring greatly improves signal quality because the amplifier is located closer to the sensor. This reduces errors due to long lead wires, connector resistance variations, electro-magnetic interference, and temperature gradients across slip ring contacts.

Connections are made through color coded solder terminals located on the slip ring rotor and a connector on the slip ring stator. The compact design of these slip rings make them ideal for applications where limited space is available.
