High frequency inductive combustion furnace

1. High frequency inductive combustion furnace output power:2200WFrequency20MHz.

2. Auto-checking: Automatic overtime/over flow alarming system.

3.The optional current/voltage/power regulator for furnace temperature control; it is applicable to samples of various materials.

4. Gas paththe high precision flow controller ensures the stability of gas flow as well the gas intake system.

Dust filter:

0.4um submicron metal filter secures thorough separation of dust from gas.

Furnace head heating

Increase conversion rate of sulfur, to get a steady analysis result.

De-dusting system:

The combustion head self-cleaning devices effective for reducing the influence of dust for the result of analysis; ash removing system for the inlet.

Detection system:

1. Circuit design: the modularized design with double CPU for the whole frame is divided into the upper and lower levels, the lower one adopt Atmega162 to control the single machine, while the electronic circuits are highly integrated stably;

2.SamplingAdopt high precision 24 leave ADS124 sampling CMOS chips,;

3.Communicationthe upper and lower machine adopt USB terminal to increase the communicating speed;

4.ConnectionInfrared detection parts and High frequency inductive combustion furnace connect with fiber, assorted with series shelter isolated circuit, avoid high frequency interfere;

5. Light sourcethe tailor-made new model platinum infrared light source has lasting caloricity and efficient spectral property

6.Analysis cell: the gilded carbon & sulfur analysis cell is fit with the high precision TSC infrared detector (1011);

7. Motor: the special-purpose aviation modulation motor is applied with satisfactory thermal stability whose life expectancy exceeds 100000 hours.

Instrument diameter and weight:

Operation system configuration

Detailed information refers to the scope of supply.

Operating software:

Adopt Deliph software,WINDOWS XP full Chinese operation interface.

Analyzing route way:

With channel management function, carbon and sulfur channel can increase, delete and edit separately without quantity limit.

Preset low carbon and high sulfur interface.

Analyzing function:

Dynamic data accumulation when analyzing, 20times sampling per second, increasing the sensitivity and accuracy.

With sample management function, can edit the name, mark of sample, also can do adding and deleting sample name.

Display function:

Separately curve frame for Carbon & Sulfur, dynamic show the data and Carbon & Sulfur release curve.

Data processing function:

Analysis results store by ACCESS data-base way, it can store data and curve every time; can search the results according to time, operator, sample name and mark any time; with curve/data storage, deduction of blankness, preset of parameters, channel selection, data statistic, result adjustment and curve preparing and other function. Can realize creating carbon and sulfur working curve and do the curve fitting in the software.

Printing function:

Printing mode diversification: Laboratory and inspection station printing mode and can self-design proper mode.

Self-diagnose function:

System self-diagnose function,can realize checking furnace head and sealing performance of the gas chamber by the soft ware.
