Description
Michigan Scientific’s B Series Slip Ring Assemblies are ideal for applications that require the slip ring to
be mounted directly on a rotating shaft. Typically used for automotive drive shaft measurement
applications, they are 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 rotating 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 B8-2/E60 is particularly useful for drive shaft applications where both torque and thrust
measurements are needed. In addition, the B8-2/E60 provides enough circuit connections for measuring
up to five amplified strain gage or thermocouple signals. Michigan Scientific’s precision strain gage and
thermocouple amplifiers, positioned on the rotation side of the slip ring, greatly improve signal quality.
They reduce the amount of errors due to long lead wires, connector resistance variations, electromagnetic
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. Each slip ring assembly includes a 15 ft. cable with a single mating connector attached. The compact-width design of these slip rings make them ideal for applications where limited space is available.
Encoder option
The encoder included in the B8-2/E60 Tubular Slip Ring Assembly produces a 60 pulse/revolution 5-volt
square wave. The TTL compatible signal is produced by a hall-effect sensor, which allows speed to be
determined down to 0 rpm. The voltage required to drive the encoder can range from 5.5 to 45 DC volts.
