Selecting Slip Ring Size

To begin selecting a slip ring size, rotating speed and sensor count requirements must be considered. The number of contacts will account for each wire going from a sensor to your data system. For example: if you need 106 sensors (assuming two wires per sensor), a 212-contact slip ring would be needed. If you require more channels than what is available on a slip ring, a switching mechanism may be needed. Additional contacts may be needed for rotating reference junctions or three- or four-wire sensors (e.g., static strain or pressure transducer).
