The invention relates to the technical field of oil quality detection, in particular to an oil quality detector and a detection method. At present, the oil quality detectors in the domestic and foreign markets use the comparison method to detect the pollution value and water content of the tested oil products, and clean oil must be used for zero adjustment every time, which is labor-intensive, time-consuming, and oil-intensive. The invention provides an oil quality detector and a detection method. The detector includes a sensor, a capacitor, a voltage converter, an operational amplifier, and a single-chip CPU. The capacitor and the voltage converter are connected to an oscillating circuit, and the oscillating circuit is connected to the operational amplifier and The single-chip microcomputer CPU is connected, and the single-chip microcomputer CPU is connected with the memory and the external device; the method monitors the oil liquid by means of oil liquid zero point memory, record, pollution value test or moisture rate test and the like. The present invention fundamentally solves the disadvantages of common detection methods, not only saves labor, time and fuel, but also solves the error caused by the change of clean oil index, and truly achieves fast, accurate and reliable detection.
Description
technical field [0001] The invention relates to the technical field of oil quality detection, in particular to an oil quality detector and a detection method. Background technique [0002] At present, the detection method of the oil quality detector in the domestic and foreign markets is to use the comparison method to detect the pollution value and water content of the tested oil. [0003] The current detection methods are: [0004] 1. First, drop the clean oil of the type of oil barrel to be tested into the sensor oil cavity, and adjust the zero point through the zero potentiometer to make the display value of the oil quality detector zero (in order to ensure the reliability of the zero point, it is often necessary to confirm several times Zero point, thus making the operation cumbersome and prolonging the test cycle). [0005] 2. Clean the oil chamber of the sensor, and then drop the measured oil into the oil chamber of the sensor. At this time, the display value of the...
