TAG Turbo and active gauge controller


The TAG (Turbo & Active Gauge) controller is a small, compact, low cost pumping system Controller, which is suitable for a wide range of vacuum applications. It is a 24V controller that is compatible with all Edwards DX and nEXT turbopumps. It contains no power source and thus you either need to supply your own power or buy the optional power supply. In addition to a turbopump it can control a backing pump, a vent valve, an air cooler and an Edwards active gauge.
The TAG Controller is controlled by an easy to use interface. A large clear LED display shows the pump speed or vacuum pressure. The compact size of the controller is ideal for use on bench-tops or suitable mobile platforms.

Features and Benefits

  • Compatible with all Edwards 24V turbopumps enabling pump control and speed display
  • Start/stop control of a backing pump for full system control (external relay may be required)
  • Turbomolecular pump start options: start with backing pump, start after time delay or start at pressure set point
  • Vent valve control options: controlled vent from full speed, vent from half speed or no vent
  • Pressure display from a compatible active gauge in mbar, Torr or Pa
