when a length of conductor is heated at one end, electrons at that end is "pushed" towards the colder end.This is due to the characteristics of the metal itself.In order to measure this movement of electrons(potential)we cannot use the same type of conductor because the net "potential" will be zero.However if a different conductor was used (different characteristics),a difference in potential can now be measured because the amount of electrons "pushed" will be different with respect to the other conductor.This is the Seebeck effect.This gives a relationship bet. voltage and temperature which can be used to measure temperature.

how do i tune dearator pr control valve using PID. we set the set point is 0.6kg/cm2 now i want 0.5 to 0.7kg/cm2 limits so what should i give p,i,d values. then pls explain how do set pid values for control valve tuning?
Hello to all....I am an Instrumentation Graduate and i am passed out in this year only.. I am unable to find the job in my core instrumentation.. so any boby tell me how to and where to search the job....please...and also tell me i there are any courses offered in the instrumentation stream so i can do it... you can send your suggestions to my mail-id i.e Ganesh20084u@gmail.com ... please..
