Infrared detect system
The core component of infrared detection pool adopts precious metal miniature infrared light source which is high-efficient and long service life.The modulation system adopts high-precision stepper motor control by the micro controller.It is realized that long-term stability of the modulation frequency and infrared pyroelectric solid light cone sensor, Narrowband filters, these instruments make the host in high detect sensitivity.and it is effective way to detect carbon and sulfur content (ppm).it simplifies the hardware design,adding the whole host reliable and anti-interference ability.
Infrared detect system
1.The circuit design: the whole machine adopts modular
design, highly integrated electronic circuits, it is very
stable and reliable, meanwhile, it is adopted multi-level
isolation so as to resolve high frequency interference
thoroughly.
2.Sampling: it is adopted 32-bit sampling chip which
belongs to America Analog Devices Company so it has
fast speed and high precision.
The Communication: it is adopted USB new data
exchange technology, so it greatly improves the
communication speed.
The Power Supply: it is adopted high quality linear
integrated military-grade power module, its output
stable and there is no problem.
3.Light Source: special new type platinum infrared light
source, it is efficient and its spectral stability.
4.The Analysis of pool: Gold-plated carbon and sulfur
5.analysis pool and High-precision pyroelectric infrared
detector.
The Motor: special aviation motor, its thermal stability
well, it has a long service life.
High Frequency Burning System
1.High Frequency Circuit: it is adopted Self-excited
directional couple take power feedback, it ensures that
output power is consistent, and it makes samples fully
burned. It is stable.
2.High-frequency High Power Circuit Design: it is
adopted 7.5kvA high-frequency pipe (actually it uses
power more than 2.5kvA, cannot add sample with
empty burn), it is reduced the load on high-frequency
combustion systems, and it improves service life.
3.Military Products: Ceramic high-power tube and
ceramic vacuum capacitor (100A).
4.High-frequency furnace output is power and power
adjustable, it is suitable for all kinds of sample
combustion analysis, a wide range of test materials,
the whole machine adopts import solenoid valve,
high-frequency Ceramic power tube etc.
5.It adopts automatic cleaning of the burner and
clean it up.
6.The control by electronic flow, the analysis of gas flow volume, the analysis of result is more stable and reliable.
7.The dust clean in the tube so as to improve measurement stable and precision.
8.The internal oxygen purification has advantages of analysis low content.
9.The main circuit over current and timeout protection. When the loop current exceeds desired point or burning time more than 6Os, the system cut the main circuit by itself, and this system can avoid high-power devices overheating damage,eliminating security risks. When the status of over current disappears, the main circuit automatically resume normal.
10.The system of high-frequency combustion and infrared detection system adopt fiber connection,cutting off direct electrical connection between the two, avoiding the burning furnace or external circuit can produce interference by cable transfers to infrared monitoring system and improves the data stable.
The Random Software
1.It is adopted WINDOWS XP color surface in Chinese/English, its interface clear and its operation very convenient.
2.The independent infrared analysis software, complete functions. It has the functions of channel selection data statistics, break point correction, results corrected, the system of detecting, system diagnostics and more than forty functions.
3.The analysis process of dynamic data integration, sampling every 32 seconds time, A/D change the frequency 150Hz-200Hz and it improves the analysis of sensitivity and accuracy.
4.The signal is tracked and its adjusted by itself.
5. Linear table of linear data high, medium and low can be corrected.
6.The process of analysis displays all kinds of real-time data and carbon and sulfur release curve.
7.There are 20 analysis channels to choose (each carbon and sulfur channels), and they can be arbitrary collocation, the choose range is very wide.
8.There are 100 carbon and sulfur release curves (each 50), it is can be stored at any time, and can be complete with carbon release curve and sulfur release curve.
9.Linearization calibration technology in full range, there are single and multi-point calibration,
10.It can be communicated with data center or reported in front of the furnace.
11.Any brand of computers can communicate with this system.
12.A variety of print output mode.
13.It can communicate with any brand of electronic balance.
