Presentation

The Michigan Scientific Slip Ring and Precision Encoder Assemblies Series SR__/PE512 are used for applications requiring both a slip ring and a precision encoder. These assemblies are available in both standard and weatherproof models. The unit is designed to mount on the end of a rotating shaft, they make electrical connections to strain gages, thermocouples, or other rotating sensors, while simultaneously providing pulses to measure rotational velocity and angular position. The slip ring brushes and rings are made of precious metals, which minimizes noise and enables the assemblies to be used for low level instrumentation signals.

This slip ring SR__/PE512 accepts up to ten circuit connections and incorporates an optical encoder that generates two outputs of 512 pulses per revolution (ppr) in quadrature and a third output of 1 ppr. The quadrature feature detects the direction of rotation, and the 1 ppr is an index pulse used as a reference point when measuring angular position. True shaft position is indicated within 5 arc-minutes, resulting in high accuracy. This is particularly important when making measurements such as torsional vibration, instantaneous velocity, and angular position. Analog output signals for angular position and rotational speed can be obtained by using these models with Michigan Scientific’s Frequency to Voltage Encoder Electronics.

Connections to the standard models are made through color coded solder terminals located on both the slip ring rotor and slip ring stator. For the weatherproof models, connections to the slip ring rotor are made through terminals or a military style connector. To provide complete weatherproof protection, the assemblies can be sealed with a rubber boot that protects the terminals on the slip ring stator, or with 3145 RTV silicone. Permanently lubricated bearings eliminate the need for routine cleaning and maintenance.
