Description
The KOMECO 400.01.020 RPM Pulse Pick-Up Sensor is a marine engine speed sensing device designed for RPM measurement and monitoring applications in MAN B&W engine control systems. It detects rotational speed signals from the engine flywheel or rotating components and provides pulse output signals for engine controllers, monitoring units, and protection systems.
This sensor is commonly used in marine automation and diesel engine control applications where accurate speed feedback is required for engine start control, overspeed protection, running status monitoring, and speed regulation systems.
The KOMECO 400.01.020 features reliable signal detection, compact mechanical construction, and compatibility with marine engine automation environments. It is suitable as a replacement component for existing RPM pickup sensor installations.

🔹 Common Questions & Answers (Q&A)
Q: What is the function of the KOMECO 400.01.020 sensor?
A: It measures engine rotational speed by detecting pulse signals from rotating mechanical components and sends RPM feedback to the engine control system.
Q: Where is this sensor commonly installed?
A: It is mainly installed on marine diesel engines and generator systems using MAN B&W related automation equipment.
Q: What symptoms indicate a faulty RPM pickup sensor?
A: Common symptoms include unstable RPM display, missing speed feedback, engine start failure, overspeed alarm activation, or incorrect speed monitoring.
Q: Can this sensor replace an existing RPM pickup sensor directly?
A: Replacement depends on mechanical mounting, wiring configuration, signal characteristics, and controller compatibility. Always verify the original part number before installation.
Q: Does the sensor require external power?
A: Most pulse pickup sensors generate speed signals through electromagnetic detection and normally do not require separate power input.
