SEE-AIRUN SP-224 Engine Speed Sensor
The SEE-AIRUN SP-224 is a robust magnetic pickup unit (MPU) designed for precise and reliable engine speed measurement in industrial applications. Engineered for durability, it features a threaded metal body for secure mounting directly into the engine block or flywheel housing. When the teeth of a ferrous gear pass by the sensor’s tip, it generates an AC voltage signal with a frequency proportional to the engine’s rotational speed. This sensor is a critical component for engine control units, governors, and tachometers, making it ideal for use in generator sets, industrial machinery, and heavy-duty vehicles.
