MKS Instruments 651C Pressure Controller

  • Self-Tuning
  • Adjustable Soft Start Function
  • Local/Remote Transducer Zeroing
  • (2) Process Limit Relays


The MKS Instruments 651C Pressure Controller is a self-tuning pressure controller for throttle valves. It can supply ±15 Volts to power and provide a readout for an attached capacitance manometer. The self-tuning feature of the Type 651 unit determines system characteristics necessary for control. This feature takes into account time constants, transfer functions of the valve and plumbing, valve gain, pump speed, and many other important parameters when determining the system characteristics. The 651 unit also includes an adjustable soft start function (to minimize turbulence in the chamber and contamination of the process), Local/Remote transducer zeroing capability, and two process limit relays to indicate if the pressure deviates from the desired trip points.
