| This intelligent carbon sulfur analyzer is mainly reflected in the following aspects: | |
| Four physical detection pools can be automatically switched at will, using VB.net software to switch between Chinese and English; | |
| Signal tracking throughout the entire process, automatic adjustment; | |
| Automatic storage of carbon and sulfur release curves, allowing for real-time comparison of carbon and sulfur release curves; | |
| The linear data in the linear table can be corrected for high, medium, and low values. | |
| Instrument characteristics | |
| Infrared detection system | |
| Circuit design: The whole machine adopts modular design, with highly integrated electronic circuits that are stable and reliable; Simultaneously adopting multi-level isolation to solve high-frequency interference. | |
| Communication: Adopting USB data exchange technology to improve communication speed. | |
| Power supply: Linear integrated module power supply is used, with stable output and no faults. | |
| Light source: A new platinum infrared light source with high efficiency and stable spectral characteristics. | |
| Analysis cell: gold-plated carbon sulfur analysis cell and high-precision pyroelectric infrared detector. | |
| Motor: Good thermal stability and long continuous service life. | |
| High frequency combustion system | |
| High frequency circuit: using a self-excited directional coupler for power feedback to ensure consistent output power, allowing the sample to burn fully and have good stability. | |
| High frequency and high-power circuit design: Using 7.5kvA high-frequency power tubes (actual usage power greater than 2.5kvA, sample air burning can be omitted) to reduce the load on the high-frequency burning system and improve its service life. | |
| ● Instrument products: ceramic high-power electronic tubes and ceramic vacuum capacitors (100A). | |
| High frequency operation circuit: automatically detects the working conditions of solenoid valves, lifting cylinders, and high-frequency furnaces. | |
| ● Automatic obsolescence/overcurrent alarm: protects the high-frequency furnace from working in a normal state. | |
| High precision flow meters are used to analyze air flow, resulting in more stable and reliable analysis results. | |
| The high-frequency furnace is equipped with a super microporous "non clogging" metal filter to ensure complete separation of dust and gas. | |
| The pneumatic furnace head automatic cleaning device cleans more thoroughly and reduces the impact of dust on the analysis results. | |
