The working principle of diesel oil temperature sensor for Kobelco excavator:
The diesel oil temperature sensor of the Kobelco excavator is the fuel float we usually say. It can be used to measure the fuel level in the way of detecting the sliding resistance. The following method can be used to measure the fuel oil. All the fuel in the fuel tank can be released, and the resistance of the sensor is measured with a multimeter in the case of the whole car's electrifying, and it is found on the float in the tank. A fine steel wire draws it, slowly, evenly pull up and down, and at the same time observe the change of its resistance value, see if there is a moment of resistance swinging in the direction of infinity. If there is, it shows that the sensor is damaged.

What is the alarm of Kobelco excavator speed sensor?
Answer: 4 Engineering modes, low idle alarm. Kobelco engine has two speed sensors. Alarm may be loose plug.
How do the hydraulic gauge of Kobelco excavator go into the soil?
1 recommend the replacement of hydraulic oil and hydraulic oil filter core (both return oil and oil should be changed). If the car has been started for a period of time, it is recommended to check the main pump to see it, after all, the components in the main pump are very precise and the price is very expensive.
2 change a hydraulic gauge, the oil scale is cheap, and then clean the filter core. If it is changed, it is better to replace the hydraulic system under the filter core or see where there is a problem.
