temperature sensor alert
we need to construct a exp bout temperature sensor involving thermocouple,resistance temperature detector and thermistor..
the objectives r to investigate the non linear characteristics,
mathematical regress model and the ideal model and
also how to model an element from experiment data for all 3 instrument above
1.thermocouple
we have tis system formula but dont understand how its applied and wat is N..
O = KI + a - N(I)
where 0 = output in mV
K = sensitivity
I = input in degree celcius
a = intersection point
N( ) = non linear equation
we also dont understand how to analyse and model the thermocouple by using the ideal formula and non-linear polynomial regression method..
2. RTD
how to convert resistance output into voltage output,and which is easiest to conduct in lab?
3. thermistor
how to compensate the self heating
..we hope u can help,thanking in advance
