cold cathode gauge sc1 series

G-TRAN series SC1 is a magnetron type cold cathode vacuum gauge. Since no filament is used, extended life between gauge replacement is assured. Maintenance is expected. Ease of maintenance reduces the cost of ownership.

Features

  • Transducer specification
    When the pressure display is not required, the following advantages can be achieved:
    – Vacuum gauge cost is reduced because the display has been eliminated
    – Smaller size frees-up control panel space
    – Wiring is reduced
  • Maintenance is greatly simplyfied
  • Filament is eliminated: No damage from exposure to atmospheric pressure
  • Control output sign: 2 setpoint output
  • Output signal: Pressure reading is a 0 to 10V Log output (non-linear output)
  • Power supply voltage: Operated by DC24V

applications

  • Process control in the pressure range of precision vacuum equipment used for semiconductor, optics and electronic parts manufacturing
  • Process control in low vacuum range for industrial equipment such as furnaces
  • Process control in the pressure range for vacuum systems with multiple process chambers, such as in-line sputtering and single wafer processing equipment
