The main technical characteristics and functions of the transformer oil moisture analyzer

Time: 2021-12-15 Author: 铧正 Click: 779 Time

     The design principle of the trace water analyzer is the Karl Fischer coulometric method, which is widely used and can measure the trace moisture of different substances. It is an ideal instrument for the moisture analysis of insulating oil.The instrument uses a powerful new-generation processor and a new peripheral circuit, excellent low power consumption; the measurement electrode signal is used as the criterion for the end of electrolysis, and its stability and accuracy are the key factors affecting the measurement accuracy. Advanced devices and methods realize the precise detection of the measuring electrode signal; further understand the electrolyte characteristics, and propose a new software compensation and correction algorithm to improve the measurement accuracy; the Chinese character graphic LCD screen has an intuitive and friendly display interface.

    Note: Users can choose batteries according to actual needs in order to achieve portable functions!

    Mainly have the following features:

    ● Use 240x128 graphic dot matrix LCD, no logo buttons, friendly interface;

    ● Use the switch constant current source electrolysis circuit (patented technology), which reduces the power consumption of the instrument;

    ● Portable instrument with battery (optional), after the battery is fully charged, it can be used continuously for more than 8 hours under the normal test state; and it has the function of battery power detection and display;

    ● The high-precision measuring electrode signal generation and detection circuit makes the judgment of the electrolysis end point fast and accurate, and has a strong anti-interference ability;

    ● Use two methods of electrolyte blank current compensation and balance point drift compensation to correct the measurement results;

    ● Three calculation formulas for users to choose, automatically calculate the moisture content;

    ● 10 levels of stirring speed adjustment; 10 levels of electrolysis gain adjustment;

    ● With automatic detection function of measuring electrode open circuit fault and short circuit fault;

    ● Automatic storage of time-stamped historical records, up to 255;

    ● The calendar clock with temperature compensation is accurate, and it can automatically record the date and time of the measurement and can run for more than 10 years in the state of power failure;

    ● With screen protection function, if the instrument is not operated for a long time, the LCD screen will be automatically turned off to prolong the service life of the LCD. Press any key to exit the screen protection state;

    ● Leave RC232 interface to facilitate communication with computer
