More Information
Features:
- Provide Power and a Set Point Signal
- Readout of Gas Flow
- Gas Correction Potentiometer
- Remote Indicating, Recording and Controlling
The MKS Instruments 246 and 247 Power Supplies/Readouts are designed to control and display any flow transducer. The flow rate set point can be adjusted either through front panel controls or remotely through the rear panel analog interface. The 246 is a single channel/single readout unit and the 247 is a four channel/sequentially selectable single readout.
647 Eight-Channel Power Supply/Readout
The MKS Instruments 647 Microprocessor-Based Multi-Channel Flow/Pressure Controller has up to eight gas flow channels and one pressure channel which allow independent or ratio-based gas flow control. The 647 is the most technologically advanced flow programmer available and is simple to operate. Its sophisticated microprocessor-based electronics allow for several standard features: menu-driven data entry format, five programmable gas recipes, gas correction factors are stored in memory, remote zero capability for all channels, RS-232 communications link, two relay contacts per channel, three levels of menus, and optional digital PID.
The 247D MKS Instruments Four Channel Power Supply / Readout may still be available for purchase and support from Artisan Technology Group beyond End-Of-Life (EOL) by the manufacturer (OEM).
Functions
Four-channel power supply and readout device for mass flow controllers/meters, featuring 3½-digit Digital Panel Meter (DPM), 0-5 VDC signal inputs, gas correction factor scaling, external setpoint and ON/OFF control capabilities, and dual signal output modes (scaled 0-2 VDC). Provides sequential display selection, TTL-compatible external control, and rear panel adjustment for gas correction factors.
Platforms
Designed for integration in laboratory and industrial gas flow control systems, the device operates within electronic instrumentation racks and interfaces primarily with MKS analog mass flow controllers and meters through 0-5 VDC analog signals. It supplies ±15 VDC power to four channels, each providing signal conditioning, set point control, and flow readout via a sequenced 3½-digit Digital Panel Meter (DPM). Communication and control are achieved through manual front panel controls, external 0-5 VDC set point inputs, and TTL-compatible ON/OFF signals. It supports gas correction scaling on the rear panel and can be integrated into larger process control systems using standard interface cables. Typical applications include multi-gas flow monitoring, set point control, and ratioed gas mixing in vacuum and semiconductor processing environments.
Applications
This equipment is typically used in vacuum processing applications, semiconductor manufacturing, and laboratory research environments. It provides power and readout functions for mass flow controllers and meters, enabling precise control and monitoring of gas flow rates. Its multiple channels and compatibility with external set points make it suitable for sophisticated flow management systems requiring accurate scaling and signal output adjustments.
