Temperature Control System

CONSTRUCTION

  1. The temperature control system is mainly consists of chamber (plant).

  2. The heater and thermocouple is placed in that chamber.

  3. The thermocouple is connected to the amplifier.

  4. The amplifier is connected to the controller.

  5. And the controller is connected to the relay. If the relay is energised, the heater is swicthed off and if the heater is doesn’t energised, the heater is switched on.

Temperature Control System

WORKING

If the temperature is increased, then that present temperature is sensed by the thermocouple. The thermocouple converts the temp into the electrical signal. That electrical signal will processed by the sensor to the amplifier for the amplification purpose.

After the amplification the amplifier transmits the signal to the controller, where the signal is measured and compared with the set point value. Then the relay gets energized and the heater will be switched off. The temperature gets decreased and controlled to the set point value.

Then the relay doesn’t gets energized and the temperature will be increased by switching on the heater. The temperature is increased until the temperature reaches to the set point value.
