1) answer :- It's depend on application of an instruments.
hence proper coating provided by instrument manufacturer.
2) answer :- I have an only knowledge about 'proximity
sensors' in my past 3 years of experience. which are used in
vibration measurement.
principle:- it emits an electromagnetic waves & by striking
the beam/metal it reflects. the reflected waves are compared
to the emitted and finally a proximation measured.
limitation :- these sensor required metal objects to detect
it or displacement of metal.
application:- huge applications in industry such as
vibration monitoring of turbine shaft, generator shaft,
motor shaft

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.
