BUD-GAS Multiple function gas blending system
1. Product introduction
BUD-GAS Multiple function gas blending system, using 10.1 inch bright intelligent large screen, equipped with 24 high-precision digital to analog conversion chip, can perfectly replace the current mainstream control instrument, and with the instrument can not achieve digital conversion and intelligent statistical functions. The system can be equipped with multiple groups of mass flow controllers and multiple electromagnetic valves. The installation platform reserves fixed installation holes and communication interfaces for different types of mass flow controllers, and users can add and expand them independently.
BUD-GAS3H High pressure gas blending system
The BUD-GAS series is divided into two types of ambient and high pressure gas blending system to achieve precise control and measurement of a single component and mixed components. It plays an important role in the scientific research and production of semiconductor and integrated circuit industry, special materials discipline, chemical industry, petroleum industry, medicine, environmental protection and vacuum and other fields.
BUD-GAS8A ambient pressure gas blending system
Equipped with a variety of scientific research equipment, provide online gas distribution (tube furnace/thermogravimetric/infrared/test equipment/chemical adsorption instrument)
2. Product advantages
Through gas metering coefficient conversion, a gas factory calibration controller can be realized to accurately control a variety of different gas.
According to the actual use, select the control gas type in the gas type setting, the mass flow controller (MFC) identifies the gas calibration type when leaving the factory. For example, nitrogen calibration factory MFC, to control hydrogen, did not consider the conversion coefficient, then the flow meter set 30ml/min, in fact, H2 flow rate is 28.57ml/min.
With mixed component gas control function, can accurately control a variety of components of the gas blending
The type and concentration of mixed components can be directly input on the interface to achieve accurate control. When the proportion of one component is input, the other component automatically completes the input to avoid input errors.
Intelligent control and statistics
(1) The working state of the mass flow controller and electromagnetic valve can be manually controlled according to the demand
(2) Working hours can be set to achieve intelligent control
(3) The system can record the running time and accumulated traffic of each working channel
