Answer Posted / s.seshasayee
The Proximitor is designed to give known output voltage changes equal to known gap changes. This is called a SCALE FACTOR. For the proximity transducer system the standard scale factor is set at 200 millivolts per mil (200mV/mil). Scale factor information can be found on the nameplate attached to the Proximitor. Scale factors are linear for a minimum of 80 mils within the systems linear range.
Average Scale Factor (ASF) =
change in gap voltage/change in gap = 18-2/0.08in =200mV/mil

sir, i preparing hpcl,ongc,barc,hal exams(instrumentation engg)pls send a placement papers
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.
