fuel level sensor cost
Our company fuel level sensor cost is cheap . If large quantity , it will be much cheaper. Welcome to contact us!
The sensing part of the dodge journey capacitive oil level sensor is a coaxial container . When the oil enters the container , the capacitance between the sensor shell and the induction electrode changes . This change is converted by the circuit and accurately compensated for linearity and temperature , and the 4-20mA standard signal is output to the display instrument .
It is used to monitor the oil supply pressure of the engine lubrication system, determine whether the lubrication system works normally, and prevent engine damage caused by lack of oil. The sensor uses the change of capacitance between the sensor housing and the induction electrode after the oil enters the container, and converts this change into the change of electric current to detect the position of the oil in the container. It is the primary link to realize automatic detection and automatic control. The oil level sensor is a measuring device with certain accuracy and law to convert the measured into a certain physical quantity that has a definite relationship with it and is convenient for application.
The fuel float simulates the detection of the fuel level by detecting the sliding resistance. The following methods can be used for measurement. Drain all the fuel in the fuel tank, measure the resistance of the sensor with a multimeter when the whole vehicle is powered on, find a thin steel wire on the float in the fuel tank to hook it, pull it up and down slowly and evenly, and observe the change of its resistance value at the same time, to see if there is an instantaneous swing of the resistance in the direction of two sides . If there is, it indicates that the sensor is damaged.
The inaccurate indication of the pointer of the oil gauge is mainly related to the contamination of the oil float by the sundries in the oil tank and the long-term energization of the oil level sensor. Firstly , The oil float is polluted by sundries in the oil tank . Second , Long time power on of oil level sensor . if the oil float is powered on for a long time in the environment of the oil tank full of sundries, a thin diaphragm will be formed on the two contacts of the oil float and the surface of the white substrate resistor, and even the conducting band on the white substrate will be completely corroded. Then can replace a fuel level sensor , the cost is cheap from us.
