bmw x5 fuel level sensor
The position of the bmw x5 fuel sensor is in the oil tank:
1.There are many kinds of fuel level sensors, such as capacitive and electronic sensors. Different designs have different shapes and working principles;
2.The old swing rod oil float is a hollow ball, which can float on the surface of the oil layer, using the lever principle. The other end of the float is a potentiometer. The amount of oil determines the height of the float. The potentiometer at the other end will reach different potentials with the height of the oil level, which will be displayed on the instrument panel;
3.The sensing part of the capacitive fuel level sensor is a coaxial container. When the oil enters the container, it causes the change of capacitance between the sensor shell and the sensing electrode. This change is converted by the circuit and carries out accurate linearity and temperature compensation, and outputs 420mA standard signal to the display instrument;
4.Electronic can be divided into resistance type , voltage type , frequency type and other output forms according to different output signals.
The sensing part is a coaxial container. When the oil enters the container, it causes the change of capacitance between the sensor shell and the sensing electrode. Application of fuellevel sensor: compact fuel level sensor, industrial grade, suitable for the measurement of oil quality with low viscosity below 5MPa and temperature below 200 ℃, and communication with various protocols can be attached .
The position of the fuel level sensor is in the oil tank. The failure of the fuel level sensor will lead to the failure of the automobile oil gauge, which is specifically reflected in:
1.The scale of the oil gauge is fast and slow: the scale of the oil gauge is fast and slow, especially in the first half of the scale, but it is almost twice as fast in the second half;
2.The scale of the oil gauge suddenly drops to zero: I often see that there are still two grids left on the oil gauge before driving, but the scale of the oil gauge will directly drop to zero after driving for a certain distance;
3.The scale of the oil gauge rises: the pointer of the oil gauge stays at a certain position all the time. Some even increase instead of decrease after driving for a certain distance.
