Answer Posted / jaywant joshi
During the measurement of Temperature from RTD, we have to
just disconnect the RTD from the control room,(as it is
externally powered, in case of thermocouple it is self
powered transducer) after disconnecting just measure
resistance of element e.g. 115 ohms.. then deduct 100 from
it...you will get say 15,,,then multiply this by 2.5..you
will get the temperature ,,approximately you will get 38
degrees..
