Termination

Termination

Multiple types of sensor leads can be terminated to the slip ring. Examples are flexible leads such as Kapton Teflon insulated wire, high temp leads such as fiberglass insulated wire, and mineral insulated cable. Wire materials such as copper, silver-plated copper, or other solderable material can be soldered directly to the PCB. Thermocouple wires of any type can be welded to special rivets installed in the PCB or tinned with silver and soldered directly to the PCB.

Wire bundle size is limited to quill shaft ID. The smaller the slip ring, the smaller the wire size must be. The number of leads will be restricted to quill shaft ID and slip ring size. When transferring thermocouples from the IBA to the slip ring, the RTDs can compensate for the temperature reference at that junction.

Aerodyn Engineering has skilled technicians who can be available to land the slip ring on your test article. Termination is typically done at the customer’s site. We also provide training for slip ring termination. We pride ourselves in supporting all aspects of the engine test to ensure proper testing and data is received. After wires are terminated, Aerodyn recommends securing leads with Aeroshim and coating the leads with epoxy to secure all leads in place.
