KZDL-800 microcomputer automatic sulfur meter

[Scope of application]

KZDL-800 microcomputer automatic sulfur analyzer is mainly used to measure the total sulfur content in coal, coke, oil and other combustible substances. The instrument can make 24 samples at a time, and can automatically and continuously send samples, realizing unattended and high automation. In addition, it has the function of external electronic balance, which can upload data online, and is widely used in power, coal, metallurgy, chemical, cement, paper, environmental protection, geological exploration and scientific research institutes and other industries.

[Technical features]

1: The vertical high-temperature cracking furnace is adopted and the modular design of components is adopted. The automatic continuous sample delivery mechanism, electrolytic cell, agitator, air purifier and other system components are assembled in a box. Reasonable structure and ingenious conception make the instrument compact and beautiful.

2: The instrument can be externally connected with an electronic balance. Automatic weighing can be achieved by pressing the key when weighing the sample. The automatic continuous sample sending mechanism can put in 24 samples at a time, and can add samples at any time during the test process. It also has the function of queue cutting and re-queuing, and the added samples can get the opportunity to determine in advance.

3: The whole process of the test after sample loading can be unattended, improving the test efficiency. The determination process is automatically carried out by program control: fully automatic continuous sample delivery, fully automatic control of the start and end of the test, fully automatic coulometric titration, fully automatic data processing and data storage, and data printing. In addition, the instrument has networking function, which can realize data remote sharing and data report remote uploading.

4: The coulometric titration electrolytic current adopts the constant current scheme, and the coulomb integration is realized by software to ensure the titration result. The system error can directly achieve the function of self-dynamic multi-point correction through software, and more ensure the test accuracy and accuracy of high, middle and low samples. The test result is superior to the national standard, with good repeatability and high precision.

5: The furnace is made of new energy-saving materials with good thermal insulation performance, fast heating speed, environmental protection, low carbon, energy saving and high efficiency. PID temperature control precision is high, effectively protecting the service life of furnace and silicon carbon tube. In addition, the air blowing function of the sample is added, so that the sample can be quickly and completely burned to ensure the test accuracy.

6: The gas circuit adopts a new structure. It is convenient to replace the silica gel loading and unloading drying tube, with good air tightness, low failure rate, and more stable and reliable gas source.

7: The whole structure of the instrument is designed with the modular idea of components. The components and modules are easy to disassemble and can be interchanged, which is very convenient for the installation, commissioning, maintenance and subsequent after-sales service of the instrument. The automatic continuous sample sending mechanism is also a component, which can realize the exchange of batch tables and tables, which is very convenient and can solve the worries of users.

8: The system is designed with special fault diagnosis and detection procedures. During operation, each functional part of the real-time monitoring instrument has the function of fault judgment and alarm prompt. In addition, it also has a powerful debugging menu, which facilitates the on-site installation and debugging of the instrument, as well as the diagnosis and troubleshooting. In addition, remote diagnosis and technical support can also be realized through the Internet.

9: The instrument end control system adopts the new ARM series single chip microcomputer from the United States, which has fast calculation speed and strong control ability. The software is designed with embedded multitask operating system, so the program structure performance is stable and reliable, and the anti-interference ability is strong. USB mode supporting hot plug can be selected for communication with microcomputer, which is convenient for users to build one machine with multiple controls

10: The microcomputer-side test software supports WINXP, WIN7, WIN8, WIN10 and other operating system platforms, and the system is stable and reliable. The human-computer interaction interface is friendly, which is very convenient for operators to learn and use.
