Abstract

This application discloses a calibration device and method for a polymer film capacitor oil moisture sensor. The calibration device is mainly composed of a constant temperature and humidity box, a standard hygrometer, and a computer for recording data. The calibration method uses the calibration method for detecting the relative humidity of the air Methods Instead of the calibration method of directly detecting the water activity of oil, the polymer film capacitive oil moisture sensor was calibrated, and the sensor calibration curve was obtained. In addition, the calibration method can also realize temperature compensation, which plays an important role in improving the accuracy of the sensor. The main purpose of the calibration method of the present invention is to solve the problems of the existing calibration methods such as cumbersome steps, long calibration period, difficulty in oil sample configuration and storage, calibration accuracy is easily affected by factors such as oil type and aging degree, and has the advantage of not being affected by the type of oil The advantages of simple operation and short test cycle.

Description

technical field [0001] The invention relates to an oil sensor calibration technology, in particular to a polymer film capacitor oil moisture sensor calibration device and method. Background technique [0002] When the oil (mainly lubricating oil, hydraulic oil, fuel oil) is polluted by water, it will seriously affect the performance of the equipment, and may even cause serious accidents. The oil moisture online monitoring sensor based on polymer film can be used to measure the water activity of various oils, which is of great significance to the protection of aircraft and aviation equipment. However, the calibration of the oil moisture online monitoring sensor requires a large number of standard oil samples that are difficult to configure, resulting in a long calibration period and poor calibration results. [0003] According to the determination method of oil moisture in GB / T11133-1989, test the oil moisture content of each standard oil sample, and then use it as a standar...
