This article describes the installation method and adjustment method of Komatsu PC200-7 engine speed sensor, and how to judge the fault of the engine speed sensor of the excavator.
How to install and adjust Komatsu PC200-7 engine speed sensor?
First, the sensor is screwed into the engine flywheel shell, when the gear ring is touched, the 1 + 1/6 ring is returned, then the output voltage of the engine idling speed sensor is about 1V, and the output voltage of the engine should not be higher than 3.5V. at high speed.
How to judge whether the engine speed sensor of the excavator is out of order?
By monitoring the engine speed, we can know whether the output voltage and internal resistance of the speed sensor are normal.

What are the conditions for measuring the rated speed of the Komatsu PC300-7?
Answer: the engine water temperature 45-55 degrees, the hydraulic oil temperature 45-55 degrees, the A mode, the throttle knob maximum position, the automatic speed reduction, the rotary locking switch ON, the bucket overflow condition measurement its speed.
On the Komatsu PC450-7, what are the sensors for monitoring engine speed and timing angle?
A: there are three sensors. The engine speed sensor is used to monitor engine speed; G sensor is used to monitor the injection timing angle; Ne sensor is used to monitor the camshaft timing.
