Answer Posted / george mathews

Neither temperature transmitter not the thermocouple or Rtd
can control the process. Because as we know Thermocouple and
RTD are nothing but measuring medium , their only work is to
measure the temperature , and for the transmitter it nothing
but a transducer whose only work is to send the measurement
in d form of mA (4 to 20 mA.)

How earthing can be checked????
