How to gennerate earth leakage monitoring alarm for solenoid valves in control system?..

Answer / p n vadalia

Earth leakage detector is readily available for detecting
earth leakage in 24 VDC, and 110/ 230 VAC supply and it can
be connected on distribution bus bar. This device will
generate alarm when leakage is observed. you had connected
this device at bus bar and on receipt of alarm, for further
identification can be done with the help of multimeter by
measuring individual branch voltage with respect to earth,
here supply vo;ltage is considered floating.

when an eddy current probe is installed inside of a turbine or compressor in case of probe problem same as:crash of head of probe,changing the scale factor because of low measuring gap(physical gap is ok(example=1.14mm)but voltage is reduced(example=-6 volts),is any way to check the probe,when the ohm of probe is ok.thank you,(Karim Tavakoli)

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?
