Which device uses a magnetic plug to attract metal particles within the transmission and often indicates wear with a warning light?

• A. Chip Detector
• B. Center of Pressure
• C. Chord
• D. Blade Twist

Answer: (A)

The device being described is a chip detector. It sits in the transmission’s oil path as a magnetic plug, so ferrous wear particles circulating in the oil are attracted to and trapped by the magnet. As metal debris accumulates, a sensor or switch detects the buildup and typically triggers a warning light, signaling that wear is occurring and maintenance should inspect the geartrain or bearings. This allows early detection of issues before a failure. The other terms refer to flight or blade geometry and have no role in monitoring metal debris in the transmission.
