52046 Measurement of temperature is an important task in a large number of physical processes. A transducer is a device which converts the temperature information into an electrical signal, usually voltage, for an automated processing. A very wide variety of temperature transducers are commonly available which differ from each other with regards to these: Range of operation, Sensitivity, linearity, Accuracy, Stability, Repeatability and Speed of response The present experiments have been designed to study the input-output characteristics of some common transducers like, thermistors (PTC and NTC), thermocouple, semiconductor sensors and may be extended to also study the temperature coefficients of resistance.
