Answer Posted / manish parate
the output of thermocouple is mV so check the mV in diff
temperatures and the output of RTD is resistance so measure
the resistance at normal temp it should be greater or equal
to that ohm specific of RTD type .For Example if it is PT100
so it will shows minimum 100 ohm if RTD is in working condition.
Diff bet T/C and RTD
both are used to measure temperature but RTD is more
accurate than T/C
RTD can be used upto 800 deg but T/C can be used upto 1750 deg

How will you calibrate PID controller? explain with example.
Define the difference between a stable versus an unstable controlled system and some of the tools you might use to be able to detect when this is happening and assumptions used for control system application design that could contribute to instability
you must show the examples application and give at least 4 types of transducer/sensors that can minimize the failure during the manufacturing of the resistors.
