Classification based on property is as given below: Temperature - Thermistors‚ thermocouples‚ RTD’s‚ IC and many more. Pressure - Fibre optic‚ vacuum‚ elastic liquid based manometers‚ LVDT‚ electronic. Flow - Electromagnetic‚ differential pressure‚ positional displacement‚ thermal mass‚ etc. Level Sensors - Differential pressure

CHAPTER 1 1.1 Introduction: After going through tedious working days isn’t it a wonderful thing if people can just relax on the sofa and control the temperature in the living room‚ just with single button the room temperature can be controlled automatically so when the room temperature is too cold the heater will operate to produce a regulated temperature and when the room temperature is too high the cooling system will operate to produce the desired temperature. 1.2 Objectives: There are

I. Temperature Measurement 1. A thermometric property is a physical property that changes in a known way with temperature‚ and can therefore be used to measure temperature. The substance used as a thermometer must have a property that varies proportionally / linearly with temperature. [ In other words: When objects are heated or cooled‚ their temperatures change‚ along with some of their properties‚ these properties are known as Thermometric Properties.] Two commonly used thermometric properties
