Advantages and characteristics of high frequency infrared analyzer
Overall structure
The whole machine adopts modular and integrated design, the connection routes of the gas system are greatly reduced, and the gas system of the whole machine is more concise and reliable. The circuit system adopts large-scale integration. The power system adopts two solid-state power modules. The power module has a short-circuit protection function, which is resistant to current impact, dust-proof, simple and reliable; the connection uses flat connectors instead of slots, which improves the reliability of the entire circuit. Reliability and connection reliability between lines.

Air system
According to the principle of aerodynamics, multi-channel oxygen supply, automatic back-flushing and dust removal, and automatic cleaning of the furnace head are designed to effectively reduce the influence of dust on the analysis of sulfur elements, and a constant temperature device for the furnace head is added to reduce the influence of temperature on the analysis results. ring, especially when the analysis of sulfur is more stable. The air pipes and air joints are all designed for quick connection and plugging. The solenoid valves and cylinders are imported from AirTAc and have a service life of more than one million times. The cylinders adopt oil-free lubrication technology, which is suitable for harsh site environments and fundamentally It solves the reliability and sealing problems of the gas system that are common in domestic products .

Infrared detection system
The core component infrared detection pool uses high-efficiency, long-life precious metal miniature infrared light sources and metal reflectors; The modulation system adopts a high-precision DC digital stepping motor controlled by a single-chip microcomputer to achieve long-term stability of the modulation frequency , combined with military aviation-grade infrared pyroelectric solid light cone sensors, narrow-band filters, and high-precision A/D The sampling card makes the whole machine have extremely high detection sensitivity, which can effectively detect the content of carbon and sulfur in ppm level .

linearization scaling
Infrared carbon and sulfur analyzer is to analyze the content of carbon and sulfur elements in substances by detecting the absorption of infrared radiation by CO2 and SO2 gases ; linearization calibration is the key technology in instrument data. Because Lambert-Beer's law conforms to the exponential law, and because the infrared filter has a certain bandwidth, the gas absorption coefficient is not constant, so it is very difficult to obtain the linearization calibration of the integral area. We have made major breakthroughs in the design of the calibration mode, calculation method, and calibration software, and have achieved good linearity in the full range.
