TEMPERATURE CONTROLLER

[attachment=17372]

Objective:
The objective of this project is to control the temperature level in boiler tank automatically with help of Programmable Logic Controller.
Scope:
Automation is a concept that has become a keyword in the industry today. A product that is highly reliable quality yet cost effective only services in the competitive today. This can be achieved effectively only by a good automotive system. Automation is essential for increased productivity and improved quality, reduction process inventory, increased safety of working personal etc. Existing trends in control automation includes the conventional relay logic planes, computer based controls as in direct numeric and computer controls, transfer machines etc. The latest trend in logic control is the Programmable Logic Controller.
This project is very useful to many industries Applications where the boiler temperature is maintained to certain level.



Advantage:
1. Low power consumption.
2. PLCs are easy to program and install and PLC editing feature allows program changes.
3. There is no fluctuation when internal relays between turned on and turned off.
4. The speed for PLC logic operation is determined by scan time which is of the order of millisecond.
Application:
The temperature level monitoring and controlling system can be used in many industries Applications where the boiler temperature and water tank temperature is maintained to certain level.
