O2 Analyzers Principle:- the basic principle of that
analyzer is Paramagnetic system its installed the coil and
when we need to measure the gas we generate the e.m.f Oxygen
elements drooped there then we measured the value.

Answer / bapun

The working principle of advanced optimum analyser is
different from the easy line gas analyser.

Answer / vijay krishna

for analysing the oxygen percentage in atmp ferromagnatism
principle is used.o2 consists of magnatism property when
ever the o2% will be less whaet bridge will be unbalanced
and give the signal.

Answer / shayan ali

In combination with the gas analyzer system the solution ensures effective monitoring of the primary and secondary combustion, validates the clinker quality, minimizes the fuel costs through optimized combustion control and supports a safe operation.

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.
