PC series pressure controller are developed based on the advanced technology of CS series. It is strictly in accordance with SEMI standards with high precision, fast response, good repeatability, convenient use, easy communication, scalability and compatibility. There are front pressure control and back pressure control. In addition to standard RS485 output signal, it also provides analog I / O signals. PC series products can be used in semiconductors, photovoltaics, fuel cell, and other voltage control fields.
Flow display and totalizer are used to provide working power, operation control, flow setting, flow digital display and cumulative flow for gas mass flow controller (MFC) and mass flow meter (MFM) Channel, a flow display with multiple channels can be equipped with multiple MFC / MFM, they can work independently of each other.
The gas path plate is the solution of the gas path conveying system developed by the Seven Star flowmeter. Through the design, processing and testing of the gas path schematic diagram, the product realizes the pressure regulation, purity filtration, flow control and other functions of various process gases with diaphragm valve, pressure regulating valve, pressure sensor, filter, MFC and other parts. At present, the traditional VCR type gas path plate and gas are commonly used in the market The integrated gas system, i.e. IGS gas path plate, is capable of undertaking both gas path plate businesses and seven star flowmeter.
With the development of semiconductor field, higher requirements are put forward for miniaturization of parts and components. The traditional VCR gas circuit disk is difficult to meet the requirements. IGS type gas circuit disk emerges as the times require. It has the characteristics of direct gas transportation, small volume, easy installation and maintenance, which is the development direction of future gas transmission system; After years of research and development experience of MFC, the IGS gas path plate of the Seven Star flowmeter has the advantages of high sealing, high precision and high integration, and can rely on the special gas laboratory established by the Seven Star flowmeter to research and measure the special gas, so as to ensure the high accuracy of the special gas control of the IGS gas path plate.
Gas Circuit System
The PC100-D product is designed with straight channel, equipped with piezoresistive silicon pressure sensor and digital circuit board, which supports wide power supply (+ 15V ~ 24V), and supports both digital signal and 0 ~ 5V analog signal at the same time. It is possible to operate the instrument completely digitally or it can be operated in analog mode with digital monitoring. PC100-D series have high control accuracy, fast response time (< 1s), corrosion resistance and insensitive position. The client software and secondary development of control and acquisition is available through the open protocol.
