REAL TIME TEMPERATURE CONTROL BY VIRTUAL INSTRUMENTATION

REAL TIME TEMPERATURE CONTROL BY VIRTUAL INSTRUMENTATION

All the industrial application processes are mainly dependent on temperature variations .We need to maintain a constant temperature or temperature pattern throughout the process. The manual methods employed are mostly inaccurate and time consuming which can be made accurate by automating the manual temperature controls. These automated methods are efficient and highly productive when compared with manual methods. This is mainly achieved by the use of computer and aided circuits and soft wares. There are many ways to carry on this in which we have selected the method of implementing virtual instrumentation principles. Here we depict a real time temperature control of a chamber consisting of a medium (air or water) using virtual instrumentation software namely, LABVIEW. Project’s basic circuitry comprises of a heating chamber, a heater, a computer with lab view installed for controlling and a temperature transducer for measurement and feedback purposes. The LABVIEW v8.0 is selected as it is a completely platform independent, highly emulating, real time monitoring and control software.
