PCT52 – Temperature Control


PCT52 – Temperature Control

PCT52 is a visible and easy to understand temperature control process.


PCT52 is a visible and easy to understand temperature control process.

A fan blows air over a heater with radial fins and through a vertical clear acrylic duct. Sensors measure the surface temperature of the heater and the air temperature in the duct. This allows two different control implementations to be demonstrated with very different parameters, i.e.

  • Temperature control of the heater surface (Direct Heating)
  • Temperature control of the air (Indirect Heating)

In each case the temperature is controlled by varying the heater power and repeatable disturbances implemented by switching the fan speed, hence allowing direct comparison of different controller settings.
