* Completely self contained stand – alone system.

* Demonstrates the principle and working of a Proportional Integral Derivative (PID) control system with actual process.

* Supply required 230V, 50 Hz AC.

* Complete system consists of a process unit with process and control unit with sensor.

* The process unit consists of an aluminium rod as the process which is heated by 3 high wattage bulbs (100 watts each). A temperature of above 80^{0}C can be attained.

* The control unit consists of an RTD PT 100 sensor probe with connecting facilities, its sensor input circuit P.I.D. control circuits, power output circuit.

* Built – in analog meters to measure deviation (± 20^{0}C) between set and process value and % output power (0 – 100%).

* Built – in set value adjustment from 0 to 100^{0}C.

* Built – in facilities to vary proportional gain, integral time and derivative time (coarse & fine adjustments).

* Built – in facility to connect a fan (not provided) for forced cooling for creating external disturbance.

* Study of effects of integral, derivative and proportional action:

1. Proportional Control (P)

2. Proportional Integral Control (PI)

3. Proportional Derivative Control (PD)

4. Proportional Integral Derivative Control (PID)

* Multi – coloured test points are provided at various stages in the circuit to observe the waveforms and voltages.

* Set of required patch cords.

* Housed in an elegant cabinet with a well spread intelligently designed circuit layout on front panel.

* Strongly supported by a comprehensive instruction manual complete with theory and operating details.
