TEMPERATURE CONTROLLER AND COMPARISION OF DIFFERENT TEMPERATURE SENSORS TYPE

ABSTRACT This temperature controller is designed keeping in mind the industry requirement of monitoring the applications depends on proper regulation of temperature. This is done, using an assembly of various electronic components such as thermo couple, op-amps as amplifier and comparator, transistor as switch to control the indicating instrument used. The goal of any temperature controller design is to keep the temperature of the target device on the desired value defined by the user as accurately as possible and using as little energy as possible. The very control of temperature can be achieved by causing heater power to be simply switched on and off according to an under or over temperature condition respectively. Ultimately, the heater power will be regulated to achieve a desired system temperature but refinement can be employed to enhance the control accuracy. In this paper we have study the comparison of temperature sensor type
