ABSTRACT

A temperature monitoring system which can be used to monitor the temperature of industrial processes has been designed and implemented in the course of this project. This system relied upon a controller which is connected to temperature sensors. The controller compares the actual temperature to the desired control temperature, or set point, and provides an output to a control element. Mostly the control element is a heater. The controller is connected to a Personal Computer (PC) using RS232 protocol, so that the current temperature can be seen on the PC. This system offers flexibility to controlling operations by providing a user-interface from which the temperature set-point can be easily changed. It is believed that this project will remove rigorous and unnecessary monitoring and controlling activities and hence ensure cheaper and faster product output.
