The probe of a capacitance-type fuel level gauge is essentially. This product can not only overcome the above shortcomings of the traditional fuel level sensor, but also make a qualitative leap in the accuracy, stability and other indicators. It has the characteristics of high data accuracy, strong stability, long service life and so on. The specific advantages are as follows:
1、 Overcoming data jitter
CR-616 capacitive automobile fuel level sensor adds intelligent damping circuit to effectively eliminate the phenomenon of fuel level output signal jitter caused by vehicle bumps.
2、 Overcoming temperature difference
A special temperature compensation circuit is adopted inside the transmitter, which can overcome the influence of temperature difference caused by temperature change on fuel level acquisition, thus more conducive to accurate fuel level measurement.
3、 High stability
The traditional fuel level sensor is easy to produce bubbles in the fuel tank in the harsh road conditions, which affects the accuracy of fuel level measurement. CR-616 high-precision capacitive fuel level sensor for automobiles can effectively overcome the generation of foam and greatly enhance the stability of the sensor through special processing;
4、 Excellent quality and performance
The optimized circuit design is adopted, and the components used are military-grade components, ensuring the stability and reliability of the circuit.
5、 Long service life
Through special treatment of the product, its firmness, seismic resistance and pressure resistance are significantly improved, and its service life is effectively extended.The capacitive fuel level sensor uses the capacitance formed between the probe and the container to change linearly with the liquid level, and converts the change of the liquid level into a linear output, which can directly display the liquid level height or send it directly to remote monitoring through wireless transmission. system. The same sensor can change the measurement medium or change the installation environment at any time, and can automatically adapt and measure accurately without recalibration, and is not affected by dielectric constant and temperature changes. The principle of the capacitive fuel level sensor is to use the capacitance formed by filling the liquid medium between the positive and negative probes to change linearly with the liquid level, and convert the change in capacitance (that is, the change in liquid level) into a standard electrical signal output. The core component of the product adopts a highly integrated dedicated capacitance measurement chip, which has the advantages of high precision, high stability and continuous measurement after accurate temperature compensation and linear correction.
