We have 5 frame 5 GE turbines which have exhaust plenum back pressure transmitters (2 out of 3 voting). The LP leg is exposed to ambient pressure. During windy conditions, which is nearly always, these are fluctuating and causing nuisance alarms in the DCS.
I seem to recall in the past there was a device that can be installed on the LP connection to "exclude" the wind. I think it was an off the shelf item, but I can't remember from where (it was years ago). From the web I can only find a Yokogawa manual that refers to a wind-excluding pot (cylinder with a base plate).
Does anyone know the name of this device and where I can order from, or at least a picture or drawing of what a shop fabricated wind excluding pot should look like? Thanks in advance!
