The digital pressure transmitter integrates digital information technology into the pressure transmitter. The pressure transmitter built in this way has the characteristics of strong anti-interference ability, long signal transmission distance, good stability, and high precision. The software technology of the pressure transmitter Level plays an important role here. Generally, the software technology of pressure transmitter includes the following five technologies: digital filtering technology, scale conversion technology, digital zeroing technology, temperature compensation technology and nonlinear compensation technology. Many pressure transmitters use these five technologies at the same time, and some choose one or two of them. These technologies are very helpful for improving the performance of pressure transmitters. Let’s talk about the software technology of these five pressure transmitters.
Digital filtering technology: When the analog output signal of the pressure transmitter enters the microprocessor after analog-to-digital conversion, it is often mixed into random noise interference such as sharp pulses, which must be weakened and filtered. Digital filtering technology solves this problem. Disadvantages.
Scale conversion technology: The analog signal is converted from analog to digital to obtain a series of digital data, which must be converted into data with dimensions before calculation and display. This requires the use of scale conversion technology.
Digital zero adjustment technology: Various procedures are used to achieve offset calibration such as zero drift and gain drift.
Temperature compensation technology: establish a mathematical model to express the temperature, and use mathematical processing methods such as difference to effectively achieve temperature compensation, which depends on the magnitude of the effect of temperature on the output of the pressure transmitter.
Non-linear compensation technology: According to the measured characteristic curve, carry out piecewise interpolation, as long as the number of interpolation points is reasonable and enough, excellent linearity can be obtained.
When designing a pressure transmitter, it is necessary to comprehensively use these five pressure transmitter software technologies. This is very useful for designing high-end pressure transmitters. The hardware is the basis of the pressure transmitter, and the software is the pressure transmitter. Soul, taking both into account.

From March 9th to 11th, 2017, our company participated in the “2017 China (Chengdu) Oil and Gas and Petrochemical Technology and Equipment Exhibition” held in Chengdu Century City New International Convention and Exhibition Center, Sichuan Province. The exhibition was organized by China Petroleum and Petrochemical Equipment Association, China Petroleum Southwest Oil and Gas Field Company, China Petroleum and Petrochemical Engineering Research Association, Sinopec Southwest Petroleum Bureau, etc. The company’s exhibited products (electromagnetic flowmeters, vortex flowmeters, digital pressure transmitters, wireless digital temperature transmitters, intelligent flow controllers, wireless digital pressure gauges, etc.) have won the attention and praise of customers and achieved success success!
With this professional platform, our company focuses on broadening its horizons, learning advanced, and exploring new areas of cooperation, and has extensive exchanges and negotiations with supporting enterprise customers and professional audiences who come to visit, thereby enhancing the visibility and influence of our company’s brand At the same time, we will further understand the product characteristics of advanced petroleum and petrochemical companies in order to better improve our product structure and give full play to our advantages.

Through this exhibition, our company has gained a lot. We will adopt a more mature and professional attitude to let more people know our “Anjinda” brand and understand us Anhui Jinda Instrument Co., Ltd.!

Maternal love is a star that makes wandering life find its way. Mother, nurturing us with the love of her life, laid the foundation of life. No matter where you were born, home or foreign. Everyone will think of the happy time holding the mother’s clothes. In that happy day when he did not want to grow up, it was the mother who gave us life and the most selfless love. On May 13, 2017, Mother’s Day is approaching. In order to carry forward the traditional virtues of the Chinese nation of respecting the old and loving the young, Anhui Jinda Instrument Co., Ltd. launched a Mother’s Day activity with the theme of “Strong love for peace, thanksgiving to Mother’s Day”.

At 4:30 in the afternoon, all the employees gathered in the lobby of the office building with bright red cloth on the table. Everyone excitedly picked up a pen and wrote down their thoughts, blessings and gratitude to their mother.

“Mom, I love you!” “Mom, you have worked hard!” The words are superimposed on layers; the colorful and elegant carnations in everyone’s hands are all blessing “Mom, Happy Holidays”.

Every child thrives under the pure and selfless maternal love. Mothers have worked hard to bring us up, caring, teaching, and guiding us to interpret the meaning of life step by step. As children, we should remember the kindness of our parents and repay them for their nurturing. This event allowed each of us to reminisce about the hardships our mothers put in for their own growth, understand the expectations of our mothers, know how to be grateful, and know how to care for others and society.

On the morning of August 22, our company’s party branch held a special organization life meeting for the party’s mass line education and practice activities. All party members of the company attended the meeting. In accordance with the general requirements of “looking in the mirror, dressing up, washing and bathing, and treating diseases,” all party members carefully investigated and laid out outstanding problems in the “four winds” and actively carried out criticism and self-criticism.
At the meeting, the party branch secretary briefed the preparations for the special organization life meeting, put forward specific requirements for criticism and self-criticism, took the lead in self-criticism, took the lead in investigating problems, and conducted in-depth analysis. Other party members also made serious criticism and self-criticism in the face of problems and contradictions in light of their current positions and actual work conditions. In criticism and self-criticism, everyone adheres to the party spirit, principles, open heart, treat each other frankly, do not obscure, and be unambiguous. In mutual criticism, they dare to face the problem squarely, expose the shortcomings, and point out the crux of the problem and raise the issue. The reasonable suggestions for solving the problem have truly achieved the effect of cheering and cheering. After the criticism and self-criticism were over, the party branch secretary made a statement on the special organization life meeting, and the district mayor Zhang Yi put forward requirements for the next step of party branch construction and improvement of work style. After the meeting, a democratic evaluation of party members was conducted.
