Dual Process Simulator KI-101

Looking for a low cost and configurable pilot plant
... or an analogue computer to test your controller

Dual Process Simulator KI-101

FEATURES

  • Two processes A & B can be used INDEPENDENTLY, CASCADED or COUPLED as a two-by-two multi-variable system
  • Processes synthesized from process elements which simulates both linear and non-linear dynamics
  • Process elements for simulating load disturbance and measurement noise
  • Well planned front panel for quick configuration or changing of process dynamics
  • Connection to a computer via RS232 for data and trend logging
  • Portable unit which can be readily brought to the field to demonstrate the performance of a controller or to troubleshoot a faulty controller

    Theory of Operation

    The two simulated processes are synthesized from a generic set of process elements. These elements simulate linear process dynamics such as lag, complex pole, unstable pole, and unstable zero, ... , simulates non-linear process dynamics such as deadtime, pH-type behaviour and hysteresis, ... , simulates signal source such as load disturbance and measurement noise.

    The time scale of the two processes can also be independently set at one of three available speeds (FAST, MED and SLOW),
