An experimental approach for precise temperature measurement using platinum RTD PT1000

Temperature measurement refers to the process of evaluating a current local temperature for immediate or later assessment. This research paper describes the design and development of circuit modules for lab experiments. Monitoring followed by controlling & maintaining the temperature of instruments/payloads flown in a spacecraft is very important application. Secondly, scientific laboratories require different kinds of heater/hot plates whose temperature has to be monitored and controlled precisely. Instrumentation is developed to give the appropriate electrical signal (in the range of analog inputs) to the microcontroller after signal conditioning. It provides an efficient alternative to the existing temperature measuring techniques with comparable performance. The system can also be interfaced with MATLAB or a custom made GUI to log and plot temperature time graphs.
