A magnetic Pick Up sensor functions as an AC voltage generator.
It is typically installed near the flywheel housing of an internal combustion engine, where the starter gear teeth induce a voltage pulse each time a tooth passes the sensor tip.
✅ Operating Principle:
Generates an electrical signal with each passing gear tooth.
Signal strength depends on rotation speed and sensor gap distance.
The output is used by the engine control system (ECU / PLC / SCADA) for speed, position, or rotation monitoring.
✅ Advantages:
Simple, reliable design requiring no external power supply.
Durable under high temperature, vibration, and harsh environments.
Consistent performance in marine and industrial applications.
Easy to install and maintain.
✅ Applications:
Internal combustion engines on ships or generators.
RPM measurement and speed control systems.
Rotational monitoring of shafts and mechanical drives.
Automation systems requiring precise motion sensing.
