Application of capacitive liquid level sensor in oil monitoring

In the field of transportation, accurate monitoring of oil has always been the key to ensuring safe operation of equipment and energy management efficiency. Especially in scenarios such as tank trucks, construction machinery, automobile fuel tanks, railway locomotives and oil depot tanks, how to achieve stable measurement of non-conductive oils such as diesel, gasoline, and hydraulic oil has become the most concerned issue for many users when selecting models. FST700-204 capacitive  liquid level sensor was born in this context. With its excellent stability, adaptability and intelligence level, it has shown strong competitiveness in the field of oil measurement.

The capacitive liquid level sensor adopts advanced capacitive measurement principles to accurately calculate the liquid level by detecting the capacitance change between the probe and the oil. This non-contact measurement method makes the sensor particularly suitable for various non-conductive liquids, such as diesel, gasoline, kerosene, biodiesel, hydraulic oil, etc., which greatly improves the universality of oil measurement. Compared with traditional float or pressure type liquid level sensors, it not only has a simpler structure and higher reliability, but also avoids common problems such as float jamming and oil fluctuation interference.

The capacitive liquid level sensor has also been optimized in structural design, effectively reducing the impact of oil sloshing on the measurement results. The shell material is made of high-strength aluminum alloy, which not only has excellent corrosion resistance, but also can work stably for a long time in a wide temperature environment of -40~+85℃. Its protection level reaches IP65, which can effectively prevent the intrusion of dust, oil and water vapor. It is suitable for outdoor operations and high humidity environments, and meets the actual needs of various types of engineering machinery, logistics vehicles, refueling equipment and other harsh sites.

In terms of installation and debugging, the capacitive intelligent liquid level sensor also reflects a high degree of convenience. Users can quickly complete the calibration of zero point and full range on site without special tools or complex software operations. The installation interface supports multiple methods such as G1/2 thread and M20x1.5, which is suitable for most oil tanks or storage tanks on the market to meet the diverse installation needs of different projects. In addition, Firstrate provides users with a variety of output signal options, including analog output and RS232 and RS485 digital signals, which are convenient for access to industrial automation systems or remote monitoring platforms, and can easily realize functions such as liquid level remote transmission, alarm linkage, and data recording.

The capacitive liquid level sensor uses high-precision, high-reliability and high-adaptability product strength to help users truly realize the "clear view, accurate measurement and control" of the oil state, providing solid technical support for energy management, equipment operation and safety assurance.
