WHY TEMPERATURE TRANSMITTER USED AS WE CAN CONTROL THROUGH THERMOCOUPLE/RTD

Answer Posted / aditya kaushik

When we are using the rtd/thermocouple, The output is in mv
or Ohm variation wrt temperature, that will nt be directlyy
processed by our dcs/PLC so we are using transmitters to
convert it to 4-20 ma accordingly, bt now a days rtd cards
are available widely with plc vendors so we can now a days
use directy without transmitters also,\\thnx,

aditya
