Our designed autoclave system monitors temperature, pressure and water level via different sensor's which provides input to Micro controller and PLC. PLC and Micro controller controls the boiler temperature, pressure and water level and gives out the user required values. Temperature and pressure variations are shown on LCD and user set different functions of autoclave for different surgeries such as general surgery, Ortho, heart and brain surgery, so the parameters temperature and pressure for sterilization of medical instruments sets according to the sterilization quality. We have used safety and other check valves for safety measures.Safety valve works automatically to release pressure in case of emergency. Our design is so compact it can work automatically as well as manually.enBS ThesisElectrical EngineeringThesis
