Tell me the field calibration procedure step by step with
diagram of temperature transmitter, temperature indicator,
flow indicator, level indicator, control valve,
thermocouple, pressure indicator (digital & analogue).


Answer Posted / satya

temp transmitter :-- 1st of all temp trans mitter is
connected to thermocouple or bed thermocuple or rtd , from
these thing mV IS coming .after that to operate transmitter
we give 24VDC . then temp erature shows in the
transmitter , for calibration we use hart communicater ,
temperature indiacator is calibrated by temperature bath ,
putting the TI to temp bath and get the reading if gauge
is faulty then adjust the spring in diafagram
