    Product Description

    Granville-Phillips 303 Series 303001  VPCA  /VPC-A Programmable Microprocessor Controlled Vacuum Process Controller

    The Series 303 Vacuum Process Controller (VPC) is a programmable microprocessor controlled vacuum system controller. The basic VPC operates two ionization gauge tubes over the range from 5x10-11 to 1 x 10-1 Torr.
    VPCA sequentially operates two ionization gauge tubes.
    VPCA allows the operator to program gauge tube sensitivity, electron bombardment degas power, degas time duration, gauge tube filament overpressure trip, direction/rate of change arrows, two or three digit pressure readout, and security of programs against change. Also a control is provided for maximum emission current selection and indicators for leak testing and gauge tube filament circuit deterioration warning.

    Series 303 Vacuum Process Controller Features:

    Catalog No 303001: VPC A (sequential IG), 120 VAC, 50/60 Hz, 3 Amp

    Standard on Rear Panel:

    • Remote J211 RS232C: Input/Output connector for remote control of IG On/Off, Degas On/Off, and Filament Status Output
    • Col 1 Col 2 Connectors: for IG1 & IG2 Collectors
    • IG1 & IG2 Connectors with 1 Only Cable (pin terminated)


    Options on Rear Panel:

    • IEEE488 GP-IB: provides for two-way communication between the VPC and a computer.  Functions and displays provided by the VPC front panel may be controlled and displayed by a computer.  The only functions not implemented are those which change the displayed information.
       
    • Convectron Gauge Option with Cable for 2 x Series 275  Convectron Gauges: This option permits two gauges to be simultaneously operated to provide digital pressure measurements from 1 x 10 -3 to 999 Torr of air, N2 or Ar.  Pressure of other gasses may be measured with the use of conversion charts.  Use of this option in conjunction with an ionization gauge tube, allows the system to be monitored from atmospheric pressure down to the pressure at which the ionization gauge tube is automatically turned on.
