KTA38 KTAA19 3034572 Magnetic Pickup MPU Speed ​​Sensor for Cummins Parts

product description

introduce

The 3034572 Magnetic Pickup MPU Speed Sensor is applicable to Cummins KTA38 engines and is also compatible with other engine models such as K38, G38, QSK38, and KTA38GC. However, it's not specifically designed for the KTAA19 engine, although in some cases, it might be possible to use it depending on the specific engine configuration and requirements.

### Function and Working Principle
The Magnetic Pickup MPU Speed Sensor 3034572 is used to measure the rotational speed of the engine's crankshaft or other rotating components. It works based on the principle of electromagnetic induction. As the gears or teeth on the rotating component pass by the sensor, they cause a change in the magnetic field, which induces an alternating current (AC) voltage in the sensor coil. The frequency of this voltage is proportional to the rotational speed of the component. The engine control unit (ECU) then measures this voltage signal to determine the engine speed and uses this information to control various engine functions, such as fuel injection timing and throttle control, to ensure the engine operates efficiently and smoothly.

If the speed sensor malfunctions, it may cause problems such as inaccurate speed readings, rough engine running, difficulty starting the engine, or even engine stalling. In such cases, it is necessary to check the sensor and replace it if necessary to ensure the normal operation of the engine.
