Answer Posted / mohammed abbas
transuducer is device which is going to sense the physical
parameter of the process like temp,flow,level,pressure,and
ets and convert to electrical signal which is propotional
to PV and this is primary sensing device of transmitter and
this electrical siganal is given to the secandry sensing
device which is electronic part of tranmitter which is
further condition and amplify the siganal which is required
for further for the purpose of monitoring and indication.
convertor is going to convert ac to dc ,I/P,P/I

send me last 5 years questions asked in rrb chennai, for section engineer
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.
