CUMMINS

Features & Benefits

• Magnetic pickup reads shaft speed without physical contact
• Non-contact sensing avoids wear from touching the spinning shaft
• Feeds the over-speed protection strategy real-time shaft data
• Threads into the existing compressor housing port directly

Cummins Turbo Speed Sensor

The Cummins Turbo Speed Sensor reads turbine shaft rotational speed magnetically, without any physical contact with the spinning shaft itself. That non-contact design matters because the shaft spins fast enough that any contact-type sensor would wear out quickly or interfere with rotation. Over-speed protection built into the engine control strategy depends entirely on this reading staying accurate, since a turbo spinning past its rated limit can fail catastrophically within seconds. The Cummins 5550091 threads into the same compressor housing port the factory sensor used, so installation needs no special tools.
