I work on several Deepwater offshore production facilities. We are having two different but still related problems with our magnetorestrictive transmitters located in extreme high vibration process areas.
First we occasionally lose signal for no apparent reason back to the control system from our magnetorestrictive level transmitters attached to bridles/chambers off the side of our vessels. We have tried several different manufacturers of transmitters, debounce timers, different ways of mounting and other common practices. It is not a wiring or input card issue. We have high loss of end devices. We know it is attributed to vibration. We are looking for recommendations for a more robust/resilient transmitter that can handle this extreme vibration without having to modify our bottom flanged design on our chambers if possible (originally made by k-tek and jogler. Anyone have any experience in extreme vibration and can recommend anything?
Next we have magnetic floats in these chambers. We were recently told the floats may be losing magnetism and causing issues, personally I have never heard of this and wonder if anyone else has run into this type of issue.
