I was working on calibrating turbidity transmitters
endress+hauser at effluent polishing plant.We calibrated
using NTU buffers.What happened is that when we immersed
the sensor, everytime we raise and lower the sensor
gradually, the reading will vary.my question is that is
there any specifications on what is the required distance
from the bottom of the container with buffer to the face of
the sensor?Is it ok to install the sensor in a medium which
has turbulence specially if bubbles are present?
Can Any body tell me about the Contact or Email id of any
good Consultancy which help me to find a job in
Instrumentation Field in India .I have Six years of Work
Experience in the Same field.Please revert me back on

A PLC is programmed to drive three motors A, B and C as
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
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
[Take logic high(1) for load at 60% and logic low(0) for
load at 40%]
