Generally in which location ( JB or IO card or DCS) the
thermocouple compensation is done.Also where they measure
the atmosphere temp ( for compensation) in JB OR DCS panel?
How they compensating that atmosphere temp? is any circuit
for that ( like in rtd wheatstone bridge)?

Answer Posted / satish tumbare
Actually compensation is done in Transmitter.Transmitter
have one IC which cslculate ambient temperture.
2.If output of thermocouple is mV then compensation is done
in DCS .
In DCS one temperture sensor is connect to Analog
input card .This sensor measure room temperture using this
temperture we can calculate T/C compensation.

To become an Instrument DESIGN engineer, is there any softwares or training to become Instrument Design engineer, plz suggest me, Iam very much interested in designing.
A PLC is programmed to drive three motors A, B and C as follows : After running motor A for an hour, motor B should get ON and motor A should get OFF. And after running motor B for an hour, motor C should get ON and motor B should get OFF. And after running motor C for an hour, motor A should get ON and motor C should get OFF. (That is, a cyclic repetition with time period one hour) Now, the second condition is: If any motor gone faulty and is tripped, the consecutive motor should get ON and the faulty (tripped) motor should be eliminated from cyclic repetition. The remaining two motors should bear the cyclic repetition of one hour each. (For healthy motor take logic as high and for tripped motor take logic as low) Now, the third condition is: When motor A load(Amps) exceeds 60% of its rated load, motor B should get ON in parallel to motor A. And when both motors A & B are running in parallel, and if their load exceeds 60% of their rated load, motor C should also start in parallel to A & B. [Here the cyclic repetition is eliminated, until their loads become normal(40%)] [Take logic high(1) for load at 60% and logic low(0) for load at 40%] Now draw a flow chart or a ladder diagram to fulfill the above condition.
