Answer Posted / vikash suthar
yes it is possible. I am taliking about the controller and
cards power supply modules.They are always redundunts and
connected through diode so that if one power supply fails
the other can take the charge immediately.so it is possible
to replace one of them in running plant if the other one is
healthy.

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?
